UBUNTU-CVE-2026-89493

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate rlused against rlcount in refcount block validator ocfs2findrefcountrecinrl walks the on-disk refcount record array with: for ; i rfrecords.rlused; i++ rec = &rb-rfrecords.rlrecsi; ... rlrecs lives in a single...

CVE-2026-89542

CVE-2026-89542 is a CRITICAL (CVSS 9.8) vulnerability in the Linux kernel's SUNRPC subsystem, specifically in the gss_krb5_unwrap_v2() function. When processing GSS-KRB5 tokens, the function reads header fields at fixed offsets before validating that the token is at least 16 bytes long, causing o...

CVE-2026-89493

CVE-2026-89493 is an out-of-bounds read/write in the Linux kernel's OCFS2 filesystem module. The root cause is that ocfs2_validate_refcount_block() never validates rl_used and rl_count against the block's fixed on-disk capacity (247 records in a 4K block). A crafted or corrupted refcount block wi...

lz4: memory corruption due to an integer overflow bug caused by memmove argument

There's a flaw in lz4. An attacker who submits a crafted file to an application linked with lz4 may be able to trigger an integer overflow, leading to calling of memmove on a negative size argument, causing an out-of-bounds write and/or a crash. The greatest impact of this flaw is to availability...

ntfs-3g: Integer overflow in memmove() leading to heap buffer overflow in ntfs_attr_record_resize()
