kernel: ext4: fix uninititialized value in 'ext4_evict_inode'

An uninitialized variable flaw was found in the Linux kernel's ext4 filesystem in the inode eviction path. A local user can trigger this issue by creating filesystem operations that cause inode allocation to fail before the iflags field is initialized, followed by inode cleanup that attempts to...

kernel: ext4: silence the warning when evicting inode with dioread_nolock

In the Linux kernel, the following vulnerability has been resolved: ext4: silence the warning when evicting inode with dioreadnolock When evicting an inode with default dioreadnolock, it could be raced by the unwritten extents converting kworker after writeback some new allocated dirty blocks. It...

DEBIAN-CVE-2024-26943

In the Linux kernel, the following vulnerability has been resolved: nouveau/dmem: handle kcalloc allocation failure The kcalloc in nouveaudmemevictchunk will return null if the physical memory has run out. As a result, if we dereference srcpfns, dstpfns or dmaaddrs, the null pointer dereference...

kernel: blk-crypto: make blk_crypto_evict_key() more robust

A use-after-free vulnerability was found in the Linux kernel block layer crypto key management. When blkcryptoevictkey fails due to a key still being in-use or keyslot eviction failure during inode eviction, the function returns an error but leaves the key linked in keyslot management structures,...

kernel: Kernel: Denial of Service via resource leak in drm/ttm

A flaw was found in the Linux kernel's Direct Rendering Manager DRM subsystem, specifically within the TTM Translation Table Manager component. A local attacker with low privileges could exploit this vulnerability due to a resource leak that occurs during certain eviction errors. This could lead ...

kernel: memcontrol: ensure memcg acquired by id is properly set up

In the Linux kernel, the following vulnerability has been resolved: memcontrol: ensure memcg acquired by id is properly set up In the eviction recency check, we attempt to retrieve the memcg to which the folio belonged when it was evicted, by the memcg id stored in the shadow entry. However, ther...

kernel: blk-mq: release crypto keyslot before reporting I/O complete

A flaw was identified in the block multi-queue blk-mq subsystem of the Linux kernel where the crypto keyslot associated with a block I/O request could be released after upper layers have been notified that the I/O operation completed. Under certain conditions, this could lead to a use-after-free ...

Denial of service in Kubernetes

The Kubernetes kubelet component in versions 1.1-1.16.12, 1.17.0-1.17.8 and 1.18.0-1.18.5 do not account for disk usage by a pod which writes to its own /etc/hosts file. The /etc/hosts file mounted in a pod by kubelet is not included by the kubelet eviction manager when calculating ephemeral...
