In the Linux kernel, the following vulnerability has been resolved: um: ubd: Do not use drvdata in release The drvdata is not available in release. Let's just use container_of() to get the ubd instance. Otherwise, removing a ubd device will result in a crash: RIP: 0033:blk_mq_free_tag_set+0x1f/0xba RSP: 00000000e2083bf0 EFLAGS: 00010246 RAX: 000000006021463a RBX: 0000000000000348 RCX: 0000000062604d00 RDX: 0000000004208060 RSI: 00000000605241a0 RDI: 0000000000000348 RBP: 00000000e2083c10 R08: 0000000062414010 R09: 00000000601603f7 R10: 000000000000133a R11: 000000006038c4bd R12: 0000000000000000 R13: 0000000060213a5c R14: 0000000062405d20 R15: 00000000604f7aa0 Kernel panic - not syncing: Segfault with no mm CPU: 0 PID: 17 Comm: kworker/0:1 Not tainted 6.8.0-rc3-00107-gba3f67c11638 #1 Workqueue: events mc_work_proc Stack: 00000000 604f7ef0 62c5d000 62405d20 e2083c30 6002c776 6002c755 600e47ff e2083c60 6025ffe3 04208060 603d36e0 Call Trace: [<6002c776>] ubd_device_release+0x21/0x55 [<6002c755>] ? ubd_device_release+0x0/0x55 [<600e47ff>] ? kfree+0x0/0x100 [<6025ffe3>] device_release+0x70/0xba [<60381d6a>] kobject_put+0xb5/0xe2 [<6026027b>] put_device+0x19/0x1c [<6026a036>] platform_device_put+0x26/0x29 [<6026ac5a>] platform_device_unregister+0x2c/0x2e [<6002c52e>] ubd_remove+0xb8/0xd6 [<6002bb74>] ? • https://git.kernel.org/stable/c/23d742a3fcd4781eed015a3a93e6a0e3ab1ef2a8 https://git.kernel.org/stable/c/300e277e463e6326938dd55ea560eafa0f5c88a5 https://git.kernel.org/stable/c/509ba8746f812e45a05034ba18b73db574693d11 https://git.kernel.org/stable/c/5727343348f34e11a7c5a2a944d5aa505731d876 https://git.kernel.org/stable/c/a5a75207efae4b558aaa34c288de7d6f2e926b4b https://git.kernel.org/stable/c/2d194d951895df214e066d08146e77cb6e02c1d4 https://git.kernel.org/stable/c/e6e5a4cded9bef3a1b0a4fac815b7176eb9a18ec https://git.kernel.org/stable/c/16cf8511680809a9f20b3dd224c06d482 •

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Add sanity NULL check for the default mmap fault handler A driver might allow the mmap access before initializing its runtime->dma_area properly.

CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-53179 – smb: client: fix use-after-free of signing key
https://notcve.org/view.php?id=CVE-2024-53179
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix use-after-free of signing key Customers have reported use-after-free in @ses->auth_key.response with SMB2.1 + sign mounts which occurs due to following race: task A task B cifs_mount() dfs_mount_share() get_session() cifs_mount_get_session() cifs_send_recv() cifs_get_smb_ses() compound_send_recv() cifs_setup_session() smb2_setup_request() kfree_sensitive() smb2_calc_signature() crypto_shash_setkey() *UAF* Fix this by ensuring that we have a valid @ses->auth_key.response by checking whether @ses->ses_status is SES_GOOD or SES_EXITING with @ses->ses_lock held. After commit 24a9799aa8ef ("smb: client: fix UAF in smb2_reconnect_server()"), we made sure to call ->logoff() only when @ses was known to be good (e.g. valid ->auth_key.response), so it's safe to access signing key when @ses->ses_status == SES_EXITING. • https://git.kernel.org/stable/c/0e2b654a3848bf9da3b0d54c1ccf3f1b8c635591 https://git.kernel.org/stable/c/343d7fe6df9e247671440a932b6a73af4fa86d95 •
