use on-stack struct perf_sample_data of the caller function.
However, perf_event_bpf_output uses incorrect parameter to convert
small-sized data (struct perf_bpf_event) into large-sized data
(struct perf_sample_data), which causes memory overwriting occurs in
__perf_event_header__init_id. |

This is caused by the following error path in netfs_init():
if (!proc_mkdir("fs/netfs", NULL))
goto error_proc;
Fix this by adding ifdef in netfs_main(), so that /proc/fs/netfs is only
created with CONFIG_PROC_FS. |
| In the Linux kernel, the following vulnerability has been resolved:
igc: fix PTM cycle trigger logic
Writing to clear the PTM status 'valid' bit while the PTM cycle is
triggered results in unreliable PTM operation. To fix this, clear the
PTM 'trigger' and status after each PTM transaction.
The issue can be reproduced with the following:
$ sudo phc2sys -R 1000 -O 0 -i tsn0 -m
Note: 1000 Hz (-R 1000) is unrealistically large, but provides a way to
quickly reproduce the issue.
PHC2SYS exits with:
"ioctl PTP_OFFSET_PRECISE: Connection timed out" when the PTM transaction
fails
This patch also fixes a hang in igc_probe() when loading the igc
driver in the kdump kernel on systems supporting PTM.
The igc driver running in the base kernel enables PTM trigger in
igc_probe(). Therefore the driver is always in PTM trigger mode,
except in brief periods when manually triggering a PTM cycle.
When a crash occurs, the NIC is reset while PTM trigger is enabled.
Due to a hardware problem, the NIC is subsequently in a bad busmaster
state and doesn't handle register reads/writes. When running
igc_probe() in the kdump kernel, the first register access to a NIC
register hangs driver probing and ultimately breaks kdump.
With this patch, igc has PTM trigger disabled most of the time,
and the trigger is only enabled for very brief (10 - 100 us) periods
when manually triggering a PTM cycle. Chances that a crash occurs
during a PTM trigger are not 0, but extremely reduced. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ngbe: fix memory leak in ngbe_probe() error path
When ngbe_sw_init() is called, memory is allocated for wx->rss_key
in wx_init_rss_key(). However, in ngbe_probe() function, the subsequent
error paths after ngbe_sw_init() don't free the rss_key. Fix that by
freeing it in error path along with wx->mac_table.
Also change the label to which execution jumps when ngbe_sw_init()
fails, because otherwise, it could lead to a double free for rss_key,
when the mac_table allocation fails in wx_sw_init(). |
| In the Linux kernel, the following vulnerability has been resolved:
eth: bnxt: fix missing ring index trim on error path
Commit under Fixes converted tx_prod to be free running but missed
masking it on the Tx error path. This crashes on error conditions,
for example when DMA mapping fails. |
| In the Linux kernel, the following vulnerability has been resolved:
net: txgbe: fix memory leak in txgbe_probe() error path

in wx_init_rss_key(). However, in txgbe_probe() function, the subsequent
error paths after txgbe_sw_init() don't free the rss_key. Fix that by
freeing it in error path along with wx->mac_table.

static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: decrease sc_count directly if fail to queue dl_recall
A deadlock warning occurred when invoking nfs4_put_stid following a failed
dl_recall queue operation:
T1 T2
nfs4_laundromat
nfs4_get_client_reaplist
nfs4_anylock_blockers
__break_lease
spin_lock // ctx->flc_lock
spin_lock // clp->cl_lock
nfs4_lockowner_has_blockers
locks_owner_has_blockers
spin_lock // flctx->flc_lock
nfsd_break_deleg_cb
nfsd_break_one_deleg
nfs4_put_stid
refcount_dec_and_lock
spin_lock // clp->cl_lock
When a file is opened, an nfs4_delegation is allocated with sc_count
initialized to 1, and the file_lease holds a reference to the delegation.
The file_lease is then associated with the file through kernel_setlease.
The disassociation is performed in nfsd4_delegreturn via the following
call chain:
nfsd4_delegreturn --> destroy_delegation --> destroy_unhashed_deleg -->
nfs4_unlock_deleg_lease --> kernel_setlease --> generic_delete_lease
The corresponding sc_count reference will be released after this
disassociation.
Since nfsd_break_one_deleg executes while holding the flc_lock, the
disassociation process becomes blocked when attempting to acquire flc_lock
in generic_delete_lease. This means:
1) sc_count in nfsd_break_one_deleg will not be decremented to 0;
2) The nfs4_put_stid called by nfsd_break_one_deleg will not attempt to
acquire cl_lock;
3) Consequently, no deadlock condition is created.
Given that sc_count in nfsd_break_one_deleg remains non-zero, we can
safely perform refcount_dec on sc_count directly. This approach
effectively avoids triggering deadlock warnings. |
| A Cross-Site Request Forgery (CSRF) vulnerability was discovered in OpenKM Community Edition on or before version 6.3.12. The vulnerability exists in /admin/DatabaseQuery, which allows an attacker to manipulate a victim with administrative privileges to execute arbitrary SQL commands. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix null-ptr-deref in mlx5_create_{inner_,}ttc_table()
Add NULL check for mlx5_get_flow_namespace() returns in
mlx5_create_inner_ttc_table() and mlx5_create_ttc_table() to prevent
NULL pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
pds_core: handle unsupported PDS_CORE_CMD_FW_CONTROL result
If the FW doesn't support the PDS_CORE_CMD_FW_CONTROL command
the driver might at the least print garbage and at the worst
crash when the user runs the "devlink dev info" devlink command.
This happens because the stack variable fw_list is not 0
initialized which results in fw_list.num_fw_slots being a
garbage value from the stack. Then the driver tries to access
fw_list.fw_names[i] with i >= ARRAY_SIZE and runs off the end
of the array.
Fix this by initializing the fw_list and by not failing
completely if the devcmd fails because other useful information
is printed via devlink dev info even if the devcmd fails. |
| In the Linux kernel, the following vulnerability has been resolved:
pds_core: make wait_context part of q_info
Make the wait_context a full part of the q_info struct rather
than a stack variable that goes away after pdsc_adminq_post()
is done so that the context is still available after the wait
loop has given up.
There was a case where a slow development firmware caused
the adminq request to time out, but then later the FW finally
finished the request and sent the interrupt. The handler tried
to complete_all() the completion context that had been created
on the stack in pdsc_adminq_post() but no longer existed.
This caused bad pointer usage, kernel crashes, and much wailing
and gnashing of teeth. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Reset IRTE to host control if *new* route isn't postable
Restore an IRTE back to host control (remapped or posted MSI mode) if the
*new* GSI route prevents posting the IRQ directly to a vCPU, regardless of
the GSI routing type. Updating the IRTE if and only if the new GSI is an
MSI results in KVM leaving an IRTE posting to a vCPU.
The dangling IRTE can result in interrupts being incorrectly delivered to
the guest, and in the worst case scenario can result in use-after-free,
e.g. if the VM is torn down, but the underlying host IRQ isn't freed. |

| A vulnerability has been identified in Altair Grid Engine (All versions < V2026.0.0). Affected products do not properly handle error messages and discloses sensitive password hash information when processing user authentication requests.
This could allow a local attacker to extract password hashes for privileged accounts, which can then be subjected to offline brute-force attacks. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: aspeed: Add NULL pointer check in ast_vhub_init_dev()
The variable d->name, returned by devm_kasprintf(), could be NULL.
A pointer check is added to prevent potential NULL pointer dereference.
This is similar to the fix in commit 3027e7b15b02
("ice: Fix some null pointer dereference issues in ice_ptp.c").
This issue is found by our static analysis tool |
| A pre-auth SQL injection vulnerability in the email protection feature of Sophos Firewall versions older than 21.0 MR1 (21.0.1) allows access to the reporting database and can lead to remote code execution if a specific configuration of Secure PDF eXchange (SPX) is enabled in combination with the firewall running in High Availability (HA) mode. |
| A weak credentials vulnerability potentially allows privileged system access via SSH to Sophos Firewall older than version 20.0 MR3 (20.0.3). |
| Arbitrary File Write vulnerabilities exist in the web-based management interface of both the AOS-10 GW and AOS-8 Controller/Mobility Conductor operating systems. Successful exploitation could allow an Authenticated attacker to upload arbitrary files and execute arbitrary commands on the underlying host operating system. |
| SolarWinds Observability Self-Hosted
is susceptible to an open redirection vulnerability. The URL is not properly sanitized, and an attacker could manipulate the string to redirect a user to a malicious site. The attack complexity is high, and authentication is required. |
