|---|---|---|---|
| 2025-04-03 | CVE-2025-21997 | Integer Overflow or Wraparound vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: xsk: fix an integer overflow in xp_create_and_assign_umem() Since the i and pool->chunk_size variables are of type 'u32', their product can wrap around and then be cast to 'u64'. This can lead to two different XDP buffers pointing to the same memory area. Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with SVACE. | 5.5 |
| 2025-04-03 | CVE-2025-21998 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: firmware: qcom: uefisecapp: fix efivars registration race Since the conversion to using the TZ allocator, the efivars service is registered before the memory pool has been allocated, something which can lead to a NULL-pointer dereference in case of a racing EFI variable access. Make sure that all resources have been set up before registering the efivars. | 4.7 |
| 2025-04-03 | CVE-2025-22000 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm/huge_memory: drop beyond-EOF folios with the right number of refs When an after-split folio is large and needs to be dropped due to EOF, folio_put_refs(folio, folio_nr_pages(folio)) should be used to drop all page cache refs. | 5.5 |
| 2025-04-03 | CVE-2025-22001 | Integer Overflow or Wraparound vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: accel/qaic: Fix integer overflow in qaic_validate_req() These are u64 variables that come from the user via qaic_attach_slice_bo_ioctl(). | 5.5 |
| 2025-04-03 | CVE-2025-22002 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfs: Call `invalidate_cache` only if implemented Many filesystems such as NFS and Ceph do not implement the `invalidate_cache` method. | 5.5 |
| 2025-04-03 | CVE-2025-22003 | Out-of-bounds Read vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: can: ucan: fix out of bound read in strscpy() source Commit 7fdaf8966aae ("can: ucan: use strscpy() to instead of strncpy()") unintentionally introduced a one byte out of bound read on strscpy()'s source argument (which is kind of ironic knowing that strscpy() is meant to be a more secure alternative :)). Let's consider below buffers: dest[len + 1]; /* will be NUL terminated */ src[len]; /* may not be NUL terminated */ When doing: strncpy(dest, src, len); dest[len] = '\0'; strncpy() will read up to len bytes from src. On the other hand: strscpy(dest, src, len + 1); will read up to len + 1 bytes from src, that is to say, an out of bound read of one byte will occur on src if it is not NUL terminated. | 5.5 |
| 2025-04-03 | CVE-2025-22005 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix memleak of nhc_pcpu_rth_output in fib_check_nh_v6_gw(). fib_check_nh_v6_gw() expects that fib6_nh_init() cleans up everything when it fails. Commit 7dd73168e273 ("ipv6: Always allocate pcpu memory in a fib6_nh") moved fib_nh_common_init() before alloc_percpu_gfp() within fib6_nh_init() but forgot to add cleanup for fib6_nh->nh_common.nhc_pcpu_rth_output in case it fails to allocate fib6_nh->rt6i_pcpu, resulting in memleak. Let's call fib_nh_common_release() and clear nhc_pcpu_rth_output in the error path. Note that we can remove the fib6_nh_release() call in nh_create_ipv6() later in net-next.git. | 5.5 |
| 2025-04-03 | CVE-2025-22006 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: am65-cpsw: Fix NAPI registration sequence Registering the interrupts for TX or RX DMA Channels prior to registering their respective NAPI callbacks can result in a NULL pointer dereference. This is seen in practice as a random occurrence since it depends on the randomness associated with the generation of traffic by Linux and the reception of traffic from the wire. | 5.5 |
| 2025-04-03 | CVE-2025-22007 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix error code in chan_alloc_skb_cb() The chan_alloc_skb_cb() function is supposed to return error pointers on error. | 5.5 |
| 2025-04-03 | CVE-2025-2874 | The User Submitted Posts – Enable Users to Submit Posts from the Front End plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 20240319 due to insufficient input sanitization and output escaping. | 4.4 |
