| In the Linux kernel, the following vulnerability has been resolved:
ima: verify the previous kernel's IMA buffer lies in addressable RAM
Patch series "Address page fault in ima_restore_measurement_list()", v3.
When the second-stage kernel is booted via kexec with a limiting command
line such as "mem=<size>" we observe a pafe fault that happens.
BUG: unable to handle page fault for address: ffff97793ff47000
RIP: ima_restore_measurement_list+0xdc/0x45a
#PF: error_code(0x0000) not-present page
This happens on x86_64 only, as this is already fixed in aarch64 in
commit: cbf9c4b9617b ("of: check previous kernel's ima-kexec-buffer
against memory bounds")
This patch (of 3):
When the second-stage kernel is booted with a limiting command line (e.g.
"mem=<size>"), the IMA measurement buffer handed over from the previous
kernel may fall outside the addressable RAM of the new kernel. Accessing
such a buffer can fault during early restore.
Introduce a small generic helper, ima_validate_range(), which verifies
that a physical [start, end] range for the previous-kernel IMA buffer lies
within addressable memory:
- On x86, use pfn_range_is_mapped().
- On OF based architectures, use page_is_ram(). |
| WDR201A WiFi Extender (HW V2.1, FW LFMZX28040922V1.02) contains an OS command injection vulnerability in the firewall.cgi binary across five request handlers that apply insufficient input validation. Attackers can inject arbitrary shell commands through vulnerable parameters like websURLFilter, websHostFilter, portForward, singlePortForward, and ipportFilter using subshell syntax or unfiltered parameters, with payloads persisting in NVRAM and re-executing on every subsequent firewall.cgi request. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: algif_aead - Revert to operating out-of-place
This mostly reverts commit 72548b093ee3 except for the copying of
the associated data.
There is no benefit in operating in-place in algif_aead since the
source and destination come from different mappings. Get rid of
all the complexity added for in-place operation and just copy the
AD directly. |
| BusyBox before commit 42202bf contains a heap buffer overflow vulnerability in the DHCPv6 client (udhcpc6) DNS_SERVERS option handler in networking/udhcp/d6_dhcpc.c that allows network-adjacent attackers to trigger memory corruption by sending a crafted DHCPv6 response with a malformed D6_OPT_DNS_SERVERS option. Attackers can exploit incorrect heap buffer allocation calculations in the option_to_env() function to cause denial of service or achieve arbitrary code execution on embedded systems without heap hardening. |
| A weakness has been identified in FlowiseAI Flowise up to 3.0.12. Affected by this vulnerability is an unknown functionality of the component User Controller Handler. This manipulation of the argument userId/organizationId/workspaceId/email causes authorization bypass. The attack may be initiated remotely. The affected component should be upgraded. |
| In the Linux kernel, the following vulnerability has been resolved:
perf/x86/intel/uncore: Skip discovery table for offline dies
This warning can be triggered if NUMA is disabled and the system
boots with fewer CPUs than the number of CPUs in die 0.
WARNING: CPU: 9 PID: 7257 at uncore.c:1157 uncore_pci_pmu_register+0x136/0x160 [intel_uncore]
Currently, the discovery table continues to be parsed even if all CPUs
in the associated die are offline. This can lead to an array overflow
at "pmu->boxes[die] = box" in uncore_pci_pmu_register(), which may
trigger the warning above or cause other issues. |
| In the Linux kernel, the following vulnerability has been resolved:
hfsplus: ensure sb->s_fs_info is always cleaned up
When hfsplus was converted to the new mount api a bug was introduced by
changing the allocation pattern of sb->s_fs_info. If setup_bdev_super()
fails after a new superblock has been allocated by sget_fc(), but before
hfsplus_fill_super() takes ownership of the filesystem-specific s_fs_info
data it was leaked.
Fix this by freeing sb->s_fs_info in hfsplus_kill_super(). |
| In the Linux kernel, the following vulnerability has been resolved:
ipvs: fix NULL deref in ip_vs_add_service error path
When ip_vs_bind_scheduler() succeeds in ip_vs_add_service(), the local
variable sched is set to NULL. If ip_vs_start_estimator() subsequently
fails, the out_err cleanup calls ip_vs_unbind_scheduler(svc, sched)
with sched == NULL. ip_vs_unbind_scheduler() passes the cur_sched NULL
check (because svc->scheduler was set by the successful bind) but then
dereferences the NULL sched parameter at sched->done_service, causing a
kernel panic at offset 0x30 from NULL.
Oops: general protection fault, [..] [#1] PREEMPT SMP KASAN NOPTI
KASAN: null-ptr-deref in range [0x0000000000000030-0x0000000000000037]
RIP: 0010:ip_vs_unbind_scheduler (net/netfilter/ipvs/ip_vs_sched.c:69)
Call Trace:
<TASK>

nf_setsockopt (net/netfilter/nf_sockopt.c:102)
[..]
Fix by simply not clearing the local sched variable after a successful
bind. ip_vs_unbind_scheduler() already detects whether a scheduler is
installed via svc->scheduler, and keeping sched non-NULL ensures the
error path passes the correct pointer to both ip_vs_unbind_scheduler()
and ip_vs_scheduler_put().
While the bug is older, the problem popups in more recent kernels (6.2),
when the new error path is taken after the ip_vs_start_estimator() call. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix zero size inode with non-zero size after log replay
When logging that an inode exists, as part of logging a new name or
logging new dir entries for a directory, we always set the generation of
the logged inode item to 0. This is to signal during log replay (in
overwrite_item()), that we should not set the i_size since we only logged
that an inode exists, so the i_size of the inode in the subvolume tree
must be preserved (as when we log new names or that an inode exists, we
don't log extents).
This works fine except when we have already logged an inode in full mode
or it's the first time we are logging an inode created in a past
transaction, that inode has a new i_size of 0 and then we log a new name
for the inode (due to a new hardlink or a rename), in which case we log
an i_size of 0 for the inode and a generation of 0, which causes the log
replay code to not update the inode's i_size to 0 (in overwrite_item()).
An example scenario:
mkdir /mnt/dir
xfs_io -f -c "pwrite 0 64K" /mnt/dir/foo
sync
xfs_io -c "truncate 0" -c "fsync" /mnt/dir/foo
ln /mnt/dir/foo /mnt/dir/bar
xfs_io -c "fsync" /mnt/dir
<power fail>
After log replay the file remains with a size of 64K. This is because when
we first log the inode, when we fsync file foo, we log its current i_size
of 0, and then when we create a hard link we log again the inode in exists
mode (LOG_INODE_EXISTS) but we set a generation of 0 for the inode item we
add to the log tree, so during log replay overwrite_item() sees that the
generation is 0 and i_size is 0 so we skip updating the inode's i_size
from 64K to 0.
Fix this by making sure at fill_inode_item() we always log the real
generation of the inode if it was logged in the current transaction with
the i_size we logged before. Also if an inode created in a previous
transaction is logged in exists mode only, make sure we log the i_size
stored in the inode item located from the commit root, so that if we log
multiple times that the inode exists we get the correct i_size.
A test case for fstests will follow soon. |
| In the Linux kernel, the following vulnerability has been resolved:
jfs: nlink overflow in jfs_rename
If nlink is maximal for a directory (-1) and inside that directory you
perform a rename for some child directory (not moving from the parent),
then the nlink of the first directory is first incremented and later
decremented. Normally this is fine, but when nlink = -1 this causes a
wrap around to 0, and then drop_nlink issues a warning.
After applying the patch syzbot no longer issues any warnings. I also
ran some basic fs tests to look for any regressions. |
| CImg Library is a C++ library for image processing. Prior to commit c3aacf5, the nb_colors field read from the BMP file header is used directly to compute an allocation size without validating it against the remaining file size. A crafted BMP file with a large nb_colors value triggers an out-of-memory condition, crashing any application that uses CImg to load untrusted BMP files. This issue has been patched via commit c3aacf5. |
| titra is an open source time tracking project. In version 0.99.52, the globalsettings Meteor publication returns all global settings without any admin or role check. Any authenticated user can subscribe via DDP and receive sensitive configuration fields such as google_secret, openai_apikey, and google_clientid. At time of publication no public patch is available. |
| OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. Prior to versions 6.10.5 and 7.0.0-rc3, the OpenC3 password change functionality allows a user to change their password without providing the old password, by accepting a valid session token instead. In assumed breach scenarios, this behaviour can be exploited by an attacker who has already obtained a valid session token, to gain persistence in hijacked account (including admin) and prevent legitimate users from accessing the account. This issue has been patched in versions 6.10.5 and 7.0.0-rc3. |
| An issue was discovered in certain Apple products. iOS before 10.3 is affected. The issue involves the "Quick Look" component. It allows remote attackers to trigger telephone calls to arbitrary numbers via a tel: URL in a PDF document, as exploited in the wild in October 2016. |
| A vulnerability was found in the libsoup package. This flaw stems from its failure to correctly verify the termination of multipart HTTP messages. This can allow a remote attacker to send a specially crafted multipart HTTP body, causing the libsoup-consuming server to read beyond its allocated memory boundaries (out-of-bounds read). |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc4-topology: Correct the allocation size for bytes controls
The size of the data behind of scontrol->ipc_control_data for bytes
controls is:
[1] sizeof(struct sof_ipc4_control_data) + // kernel only struct
[2] sizeof(struct sof_abi_hdr)) + payload
The max_size specifies the size of [2] and it is coming from topology.
Change the function to take this into account and allocate adequate amount
of memory behind scontrol->ipc_control_data.
With the change we will allocate [1] amount more memory to be able to hold
the full size of data. |
| In the Linux kernel, the following vulnerability has been resolved:
ocfs2: validate inline data i_size during inode read
When reading an inode from disk, ocfs2_validate_inode_block() performs
various sanity checks but does not validate the size of inline data. If
the filesystem is corrupted, an inode's i_size can exceed the actual
inline data capacity (id_count).
This causes ocfs2_dir_foreach_blk_id() to iterate beyond the inline data
buffer, triggering a use-after-free when accessing directory entries from
freed memory.
In the syzbot report:
- i_size was 1099511627576 bytes (~1TB)
- Actual inline data capacity (id_count) is typically <256 bytes
- A garbage rec_len (54648) caused ctx->pos to jump out of bounds
- This triggered a UAF in ocfs2_check_dir_entry()
Fix by adding a validation check in ocfs2_validate_inode_block() to ensure
inodes with inline data have i_size <= id_count. This catches the
corruption early during inode read and prevents all downstream code from
operating on invalid data. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath
When cifs_sanitize_prepath is called with an empty string or a string
containing only delimiters (e.g., "/"), the current logic attempts to
check *(cursor2 - 1) before cursor2 has advanced. This results in an
out-of-bounds read.
This patch adds an early exit check after stripping prepended
delimiters. If no path content remains, the function returns NULL.
The bug was identified via manual audit and verified using a
standalone test case compiled with AddressSanitizer, which
triggered a SEGV on affected inputs. |
| PJSIP is a free and open source multimedia communication library written in C. When processing certain packets, PJSIP may incorrectly switch from using SRTP media transport to using basic RTP upon SRTP restart, causing the media to be sent insecurely. The vulnerability impacts all PJSIP users that use SRTP. The patch is available as commit d2acb9a in the master branch of the project and will be included in version 2.13. Users are advised to manually patch or to upgrade. There are no known workarounds for this vulnerability. |
| PJSIP is a free and open source multimedia communication library written in the C language. Versions 2.12 and prior contain a denial-of-service vulnerability that affects PJSIP users that consume PJSIP's XML parsing in their apps. Users are advised to update. There are no known workarounds. |
