CVE-2026-74362

In the Linux kernel CVE-2026-74362, the vulnerability stems from ext2_write paths where ext2_dio_write_iter() does not propagate the error returned by generic_write_sync(), potentially causing write(2) to report success for O_SYNC/O_DSYNC files even when the sync failed. The corrective pattern is...

CVE-2026-74360

The CVE-2026-74360 entry describes a Linux kernel vulnerability in BPF iterators: bpf_map_elem iterators bind their target map at attach time, bypassing the exclusivity check enforced by check_map_prog_compatibility() for excl_prog_hash. This can undermine the intended isolation of exclusive maps...
