CVE-2025-37785 – ext4: fix OOB read when checking dotdot dir
https://notcve.org/view.php?id=CVE-2025-37785
18 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: ext4: fix OOB read when checking dotdot dir Mounting a corrupted filesystem with directory which contains '.' dir entry with rec_len == block size results in out-of-bounds read (later on, when the corrupted directory is removed). ext4_empty_dir() assumes every ext4 directory contains at least '.' and '..' as directory entries in the first data block. It first loads the '.' dir entry, performs sanity checks by calling ext4_check_dir_entry() ... • https://git.kernel.org/stable/c/ac27a0ec112a089f1a5102bc8dffc79c8c815571 •

CVE-2025-23136 – thermal: int340x: Add NULL check for adev
https://notcve.org/view.php?id=CVE-2025-23136
16 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: thermal: int340x: Add NULL check for adev Not all devices have an ACPI companion fwnode, so adev might be NULL. This is similar to the commit cd2fd6eab480 ("platform/x86: int3472: Check for adev == NULL"). Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in int3402_thermal_probe(). Note, under the same directory, int3400_thermal_probe() has such a check. [ rjw: Subject edit, added Fix... • https://git.kernel.org/stable/c/77e337c6e23e3b9d22e09ffec202a80f755a54c2 •

16 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: dlm: prevent NPD when writing a positive value to event_done do_uevent returns the value written to event_done. In case it is a positive value, new_lockspace would undo all the work, and lockspace would not be set. __dlm_new_lockspace, however, would treat that positive value as a success due to commit 8511a2728ab8 ("dlm: fix use count with multiple joins").
