CVE-2026-45838

In the Linux kernel, the following vulnerability has been resolved: bpf: fix end-of-list detection in cgroupstoragegetnextkey listnextentry never returns NULL -- when the current element is the last entry it wraps to the list head via containerof. The subsequent NULL check is therefore dead code...

CVE-2026-45838

The CVE-2026-45838 entry concerns the Linux kernel BPF code: the function cgroup_storage_get_next_key() incorrectly handled end-of-list detection because list_next_entry() could wrap to the list head, making the subsequent NULL check dead code and causing -ENOENT not to be returned for the last e...

CVE-2026-31666

CVE-2026-31666 affects the Linux kernel’s btrfs filesystem. A defect in lookup_extent_data_ref() caused an incorrect return value when transitioning between leaves, due to merged err/ret handling: if btrfs_next_leaf() returns 0, ret could be overwritten from -ENOENT to 0, making a non-matching ke...

In the Linux kernel, the following vulnerability has been resolved: ima: Handle error code returned by imafilterrulematch In imamatchrules, if imafilterrulematch returns -ENOENT due to the rule being NULL, the function incorrectly skips the 'if !rc' check and sets 'result = true'. The LSM rule is...

CVE-2023-53845

CVE-2023-53845 affects the Linux kernel nilfs2 subsystem. When mounting a disk image where a metadata file’s block lookup yields an invalid virtual address, nilfs_bmap_lookup_at_level() could return the same -ENOENT code as a non-existent block, causing nilfs_mdt_get_block() to loop indefinitely ...
