| 2025-03-27 | CVE-2023-52939 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm: memcg: fix NULL pointer in mem_cgroup_track_foreign_dirty_slowpath() As commit 18365225f044 ("hwpoison, memcg: forcibly uncharge LRU pages"), hwpoison will forcibly uncharg a LRU hwpoisoned page, the folio_memcg could be NULl, then, mem_cgroup_track_foreign_dirty_slowpath() could occurs a NULL pointer dereference, let's do not record the foreign writebacks for folio memcg is null in mem_cgroup_track_foreign_dirty() to fix it. | 5.5 |
| 2025-03-27 | CVE-2023-52976 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: efi: fix potential NULL deref in efi_mem_reserve_persistent When iterating on a linked list, a result of memremap is dereferenced without checking it for NULL. This patch adds a check that falls back on allocating a new page in case memremap doesn't succeed. Found by Linux Verification Center (linuxtesting.org) with SVACE. [ardb: return -ENOMEM instead of breaking out of the loop] | 5.5 |

| 2025-03-27 | CVE-2023-52978 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: riscv: kprobe: Fixup kernel panic when probing an illegal position The kernel would panic when probed for an illegal position. | 5.5 |
| 2025-03-27 | CVE-2023-52979 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: squashfs: harden sanity check in squashfs_read_xattr_id_table While mounting a corrupted filesystem, a signed integer '*xattr_ids' can become less than zero. | 5.5 |
| 2025-03-27 | CVE-2023-52984 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: phy: dp83822: Fix null pointer access on DP83825/DP83826 devices The probe() function is only used for the DP83822 PHY, leaving the private data pointer uninitialized for the smaller DP83825/26 models. While all uses of the private data structure are hidden in 82822 specific callbacks, configuring the interrupt is shared across all models. This causes a NULL pointer dereference on the smaller PHYs as it accesses the private data unchecked. | 5.5 |
