https://notcve.org/view.php?id=CVE-2025-38323
10 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: net: atm: add lec_mutex syzbot found its way in net/atm/lec.c, and found an error path in lecd_attach() could leave a dangling pointer in dev_lec[]. Add a mutex to protect dev_lecp[] uses from lecd_attach(), lec_vcc_attach() and lec_mcast_attach(). Following patch will use this mutex for /proc/net/atm/lec.

10 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: smb: Log an error when close_all_cached_dirs fails Under low-memory conditions, close_all_cached_dirs() can't move the dentries to a separate list to dput() them once the locks are dropped. This will result in a "Dentry still in use" error, so add an error message that makes it clear this is what happened: [ 495.281119] CIFS: VFS: \\otters.example.com\share Out of memory while dropping dentries [ 495.281595] ------------[ cut here ]--------... • https://git.kernel.org/stable/c/b8ced2b9a23a1a2c1e0ed8d0d02512e51bdf38da •

CVE-2025-38312 – fbdev: core: fbcvt: avoid division by 0 in fb_cvt_hperiod()
https://notcve.org/view.php?id=CVE-2025-38312
10 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: fbdev: core: fbcvt: avoid division by 0 in fb_cvt_hperiod() In fb_find_mode_cvt(), iff mode->refresh somehow happens to be 0x80000000, cvt.f_refresh will become 0 when multiplying it by 2 due to overflow. It's then passed to fb_cvt_hperiod(), where it's used as a divider -- division by 0 will result in kernel oops. Add a sanity check for cvt.f_refresh to avoid such overflow...

CVE-2025-38269 – btrfs: exit after state insertion failure at btrfs_convert_extent_bit()

10 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: btrfs: exit after state insertion failure at btrfs_convert_extent_bit() If insert_state() state failed it returns an error pointer and we call extent_io_tree_panic() which will trigger a BUG() call. However if CONFIG_BUG is disabled, which is an uncommon and exotic scenario, then we fallthrough and call cache_state() which will dereference the error pointer, resulting in an invalid memory access. So jump to the 'out' label after calling ext... • https://git.kernel.org/stable/c/58c50f45e1821a04d61b62514f9bd34afe67c622 •

CVE-2025-38262 – tty: serial: uartlite: register uart driver in init

09 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: tty: serial: uartlite: register uart driver in init When two instances of uart devices are probing, a concurrency race can occur. If one thread calls uart_register_driver function, which first allocates and assigns memory to 'uart_state' member of uart_driver structure, the other instance can bypass uart driver registration and call ulite_assign. This calls uart_add_one_port, which expects the uart driver to be fully initialized. This leads... • https://git.kernel.org/stable/c/238b8721a554a33a451a3f13bdb5be8fe5cfc927 •

CVE-2025-38250 – Bluetooth: hci_core: Fix use-after-free in vhci_flush()

[0] From the splat, a thread close()d a vhci file descriptor while its device was being used by iotcl() on another thread.
