In the Linux kernel, the following vulnerability has been resolved: dm-pcache: clamp the tail kset read to the segment data region The tail-kset read in cachereplay, the writeback worker and the GC worker bounds its length by PCACHESEGSIZE - segoff, the raw segment size rather than the data regio...

UBUNTU-CVE-2026-89537

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Reject short RFC 4121 MIC tokens in gsskrb5verifymicv2 gsskrb5verifymicv2 reads the token ID at ptr0..1, the flags byte at ptr2, and padding at ptr3..7, then passes ptr + GSSKRB5TOKHDRLEN and cksumlen to gsskrb5micbuildsg...

UBUNTU-CVE-2026-80961

In the Linux kernel, the following vulnerability has been resolved: dm-pcache: validate kset keynum and intra-segment bounds Two more fields decoded from the cache device go unbounded. The kset keynum drives cacheksetcrc and the replay loop in cachereplay, the writeback worker and the GC worker,...

UBUNTU-CVE-2026-81007

In the Linux kernel, the following vulnerability has been resolved: ipmi: ipmb: validate write message length ipmbwrite read message fields before validating the length byte. A zero or short write can read uninitialized stack bytes. A length smaller than the SMBus header underflows the block writ...
