CVE-2026-98868 dm-pcache: reject a kset that overruns its segment

In the Linux kernel, the following vulnerability has been resolved: dm-pcache: reject a kset that overruns its segment cachereplay, the writeback worker and the GC worker read a kset of getksetonmediasize bytes and advance the position by it. A forged keynum makes that size exceed the segment's...

CVE-2026-98868

A vulnerability exists in the Linux kernel 's dm-pcache component where cache_replay() , the writeback worker, and the GC worker could be misled by a forged key_num . This causes the system to read a kset larger than the segment's remaining space, leading to an out-of-bounds memory access that tr...

CVE-2026-98867 dm-pcache: bound the logical key offset from persistent memory

In the Linux kernel, the following vulnerability has been resolved: dm-pcache: bound the logical key offset from persistent memory cachekeydecode takes a key's logical off from the cache device and later indexes reqkeytree-subtrees by it in getsubtree. An off past the device forms a subtree point...

CVE-2026-98867

The Linux kernel is affected by a vulnerability in dm-pcache where the cache_key_decode() function fails to properly validate the logical offset of a key from persistent memory. An offset exceeding the device size allows the creation of a subtree pointer outside the req_key_tree->subtrees[] ar...

CVE-2026-93198

A flaw was found in the Linux kernel's dm-pcache component. A local attacker could provide a specially crafted image with a malformed dirtytail chain. This could cause the writeback worker to enter an infinite loop, leading to a denial of service DoS condition on the system...

CVE-2026-93201

A flaw was found in the Linux kernel's dm-pcache component. An attacker with administrative privileges CAPSYSADMIN can supply a specially crafted cache device with an out-of-range segment identifier. This can lead to an out-of-bounds read and write, resulting in memory corruption and potentially...

SUSE CVE-2026-93198

In the Linux kernel, the following vulnerability has been resolved: dm-pcache: validate the persisted dirtytail chain at load The writeback worker follows the persisted dirtytail chain, which is decoded from the cache device independently of the keytail chain that cachereplay walks and bounds. A...
