CVE-2022-49769

CVE-2022-49769 corresponds to a Linux kernel fix for the gfs2 filesystem: after reading a superblock, the sb_bsize_shift field is now validated to match the expected value, preventing shift/out-of-bounds and related mount errors. The available details describe the root cause (unchecked sb_bsize_s...

CVE-2022-49768

CVE-2022-49768 is associated with the Linux kernel 9p subsystem, specifically in trans_fd/p9_conn_cancel, where a double-lock issue was reported by syzbot and is mitigated by dropping the client lock earlier after requests move to the local list. Public sources in connected documents (Astra Linux...

CVE-2022-49767

CVE-2022-49767 affects the Linux kernel 9p/trans_fd path. The issue arises because p9_mux_poll_stop() could fail to interrupt blocking kernel_read()/kernel_write() on pipes due to fd_open() not setting O_NONBLOCK, whereas socket paths already use O_NONBLOCK. A minimal patch makes O_NONBLOCK alway...
