CVE-2026-99084

The Linux kernel contains a vulnerability where iterate_dir() takes a directory's i_rwsem shared lock and holds it across iterate_shared() . This is particularly impactful for nullfs instances, where a shared inode across multiple mount namespaces can be used to cause a denial of service (DoS) . ...

CVE-2026-99083

The Linux kernel contains a heap out-of-bounds write vulnerability in the ksmbd component within the krb5_authenticate() function. The root cause is an incorrect calculation of out_len, which fails to account for work->next_smb2_rsp_hdr_off when SMB2_SESSION_SETUP is processed as a non-first e...
