| 2024-02-22 | CVE-2024-26591 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bpf: Fix re-attachment branch in bpf_tracing_prog_attach The following case can cause a crash due to missing attach_btf: 1) load rawtp program 2) load fentry program with rawtp as target_fd 3) create tracing link for fentry program with target_fd = 0 4) repeat 3 In the end we have: - prog->aux->dst_trampoline == NULL - tgt_prog == NULL (because we did not provide target_fd to link_create) - prog->aux->attach_btf == NULL (the program was loaded with attach_prog_fd=X) - the program was loaded for tgt_prog but we have no way to find out which one BUG: kernel NULL pointer dereference, address: 0000000000000058 Call Trace: <TASK> ? __die+0x20/0x70 ? page_fault_oops+0x15b/0x430 ? fixup_exception+0x22/0x330 ? exc_page_fault+0x6f/0x170 ? asm_exc_page_fault+0x22/0x30 ? bpf_tracing_prog_attach+0x279/0x560 ? btf_obj_id+0x5/0x10 bpf_tracing_prog_attach+0x439/0x560 __sys_bpf+0x1cf4/0x2de0 __x64_sys_bpf+0x1c/0x30 do_syscall_64+0x41/0xf0 entry_SYSCALL_64_after_hwframe+0x6e/0x76 Return -EINVAL in this situation. | 5.5 |
| 2024-02-22 | CVE-2024-26592 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix UAF issue in ksmbd_tcp_new_connection() The race is between the handling of a new TCP connection and its disconnection. | 7.8 |
| 2024-02-21 | CVE-2024-26582 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: tls: fix use-after-free with partial reads and async decrypt tls_decrypt_sg doesn't take a reference on the pages from clear_skb, so the put_page() in tls_decrypt_done releases them, and we trigger a use-after-free in process_rx_list when we try to read from the partially-read skb. | 7.8 |
| 2024-02-21 | CVE-2024-26583 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tls: fix race between async notify and socket close The submitting thread (one which called recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete() so any code past that point risks touching already freed data. Try to avoid the locking and extra flags altogether. Have the main thread hold an extra reference, this way we can depend solely on the atomic ref counter for synchronization. Don't futz with reiniting the completion, either, we are now tightly controlling when completion fires. | 4.7 |
| 2024-02-21 | CVE-2024-26584 | Improper Handling of Exceptional Conditions vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: tls: handle backlogging of crypto requests Since we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on our requests to the crypto API, crypto_aead_{encrypt,decrypt} can return -EBUSY instead of -EINPROGRESS in valid situations. | 5.5 |
| 2024-02-21 | CVE-2024-26585 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tls: fix race between tx work scheduling and socket close Similarly to previous commit, the submitting thread (recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete(). Reorder scheduling the work before calling complete(). This seems more logical in the first place, as it's the inverse order of what the submitting thread will do. | 4.7 |
| 2024-02-20 | CVE-2024-26581 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_set_rbtree: skip end interval element from gc rbtree lazy gc on insert might collect an end interval element that has been just added in this transactions, skip end interval elements that are not yet active. | 7.8 |
| 2024-02-12 | CVE-2023-52429 | Improper Check for Unusual or Exceptional Conditions vulnerability in multiple products dm_table_create in drivers/md/dm-table.c in the Linux kernel through 6.7.4 can attempt to (in alloc_targets) allocate more than INT_MAX bytes, and crash, because of a missing check for struct dm_ioctl.target_count. | 5.5 |
| 2024-02-12 | CVE-2024-25739 | Improper Check for Unusual or Exceptional Conditions vulnerability in Linux Kernel create_empty_lvol in drivers/mtd/ubi/vtbl.c in the Linux kernel through 6.7.4 can attempt to allocate zero bytes, and crash, because of a missing check for ubi->leb_size. | 5.5 |
| 2024-02-12 | CVE-2024-25740 | Memory Leak vulnerability in Linux Kernel A memory leak flaw was found in the UBI driver in drivers/mtd/ubi/attach.c in the Linux kernel through 6.7.4 for UBI_IOCATT, because kobj->name is not released. | 5.5 |
