kernel: net/mlx5e: Fix cleanup null-ptr deref on encap lock

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix cleanup null-ptr deref on encap lock During module is unloaded while a peer tc flow is still offloaded, first the peer uplink rep profile is changed to a nic profile, and so neigh encap lock is destroyed. Next duri...

kernel: drm/ttm: Fix a NULL pointer dereference

In the Linux kernel, the following vulnerability has been resolved: drm/ttm: Fix a NULL pointer dereference The LRU mechanism may look up a resource in the process of being removed from an object. The locking rules here are a bit unclear but it looks currently like res-bo assignment is protected ...

kernel: writeback: avoid use-after-free after removing device

In the Linux kernel, the following vulnerability has been resolved: writeback: avoid use-after-free after removing device When a disk is removed, bdiunregister gets called to stop further writeback and wait for associated delayed work to complete. However, wbinodewritebackend may schedule bandwid...

kernel: net: openvswitch: fix race on port output

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: fix race on port output assume the following setup on a single machine: 1. An openvswitch instance with one bridge and default flows 2. two network namespaces "server" and "client" 3. two ovs interfaces "server"...

kernel: wifi: ath12k: Handle lock during peer_id find

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Handle lock during peerid find ath12kpeerfindbyid requires that the caller hold the ab-baselock. Currently the WBM error path does not hold the lock and calling that function, leads to the following lockdepassertin...

mariadb: compress_write() fails to release mutex on failure

In MariaDB before 10.9.2, compresswrite in extra/mariabackup/dscompress.cc does not release datamutex upon a stream write failure, which allows local users to trigger a deadlock...

Tongda2000 is a network intelligent office system from China Tongda Tongda. A security vulnerability exists in Tongda OA 2017 11.9 and earlier versions, which originates from a SQL injection vulnerability in the parameter TERMIDSTR in the file general/wiki/cp/manage/lock.php...

mariadb: improper locking due to the unreleased lock in extra/mariabackup/ds_compress.cc

MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/dscompress.cc, when an error occurs i.e., going to the err label while executing the method createworkerthreads, the held lock thd-ctrlmutex is not released correctly, which allows local users to trigger a denial ...

mariadb: improper locking due to the unreleased lock in extra/mariabackup/ds_compress.cc

MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/dscompress.cc, when an error occurs pthreadcreate returns a nonzero value while executing the method createworkerthreads, the held lock is not released correctly, which allows local users to trigger a denial of...

kernel: ceph: fix potential use-after-free bug when trimming caps

A use-after-free vulnerability was found in the Linux kernel's Ceph filesystem client. When iterating over session caps in cephiteratesessioncaps, the session-scaplock is released temporarily, allowing another thread to remove the cap. If the cap is freed while the iteration continues, subsequent...

kernel: blk-cgroup: hold queue_lock when removing blkg->q_node

A locking flaw was found in the Linux kernel's block cgroup subsystem. When removing blkg-qnode from q-blkglist in blkgfreeworkfn, the code fails to hold queuelock. This missing lock allows concurrent access from blkgdestroyall, leading to list corruption and potential hard lockups...

kernel: mm: hugetlb: fix UAF in hugetlb_handle_userfault

In the Linux kernel, the following vulnerability has been resolved: mm: hugetlb: fix UAF in hugetlbhandleuserfault The vmalock and hugetlbfaultmutex are dropped before handling userfault and reacquire them again after handleuserfault, but reacquire the vmalock could lead to UAF1,2 due to the...

kernel: igb: revert rtnl_lock() that causes deadlock

In the Linux kernel, the following vulnerability has been resolved: igb: revert rtnllock that causes deadlock The commit 6faee3d4ee8b "igb: Add lock to avoid data race" adds rtnllock to eliminate a false data race shown below FREE from device detaching | USE from netdev core igbremove |...

kernel: wifi: rtw88: use work to update rate to avoid RCU warning

A flaw was identified in the Linux kernel’s rtw88 Wi-Fi driver drivers/net/wireless/realtek/rtw88 where the ieee80211ops::starcupdate callback was invoked within a Read-Copy-Update RCU read-side critical section without proper atomicity or deferral. The ieee80211chanbwchange function holds an RCU...

kernel: iommufd: IOMMUFD_DESTROY should not increase the refcount

A race condition was identified in the iommufd subsystem of the Linux kernel where the IOMMUFDDESTROY command incorrectly increments an object’s reference count without holding the expected exclusive synchronization destroyrwsem. This violates the assumption that temporary reference count...

kernel: ASoC: soc-compress: Reposition and add pcm_mutex

A locking issue was found in the ASoC ALSA SoC compressed audio subsystem in the Linux kernel. When DPCM Dynamic PCM compressed streams are started, several functions access resources without properly holding the card-pcmmutex lock. This triggers lock assertion warnings and can cause kernel panic...
