| 2025-02-26 | CVE-2022-49560 | Out-of-bounds Read vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: exfat: check if cluster num is valid Syzbot reported slab-out-of-bounds read in exfat_clear_bitmap. This was triggered by reproducer calling truncute with size 0, which causes the following trace: BUG: KASAN: slab-out-of-bounds in exfat_clear_bitmap+0x147/0x490 fs/exfat/balloc.c:174 Read of size 8 at addr ffff888115aa9508 by task syz-executor251/365 Call Trace: __dump_stack lib/dump_stack.c:77 [inline] dump_stack_lvl+0x1e2/0x24b lib/dump_stack.c:118 print_address_description+0x81/0x3c0 mm/kasan/report.c:233 __kasan_report mm/kasan/report.c:419 [inline] kasan_report+0x1a4/0x1f0 mm/kasan/report.c:436 __asan_report_load8_noabort+0x14/0x20 mm/kasan/report_generic.c:309 exfat_clear_bitmap+0x147/0x490 fs/exfat/balloc.c:174 exfat_free_cluster+0x25a/0x4a0 fs/exfat/fatent.c:181 __exfat_truncate+0x99e/0xe00 fs/exfat/file.c:217 exfat_truncate+0x11b/0x4f0 fs/exfat/file.c:243 exfat_setattr+0xa03/0xd40 fs/exfat/file.c:339 notify_change+0xb76/0xe10 fs/attr.c:336 do_truncate+0x1ea/0x2d0 fs/open.c:65 Move the is_valid_cluster() helper from fatent.c to a common header to make it reusable in other *.c files. | 7.1 |
| 2025-02-26 | CVE-2022-49563 | Integer Underflow (Wrap or Wraparound) vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: crypto: qat - add param check for RSA Reject requests with a source buffer that is bigger than the size of the key. | 5.5 |
| 2025-02-26 | CVE-2022-49564 | Integer Underflow (Wrap or Wraparound) vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: crypto: qat - add param check for DH Reject requests with a source buffer that is bigger than the size of the key. | 5.5 |
| 2025-02-26 | CVE-2022-49566 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: crypto: qat - fix memory leak in RSA When an RSA key represented in form 2 (as defined in PKCS #1 V2.1) is used, some components of the private key persist even after the TFM is released. Replace the explicit calls to free the buffers in qat_rsa_exit_tfm() with a call to qat_rsa_clear_ctx() which frees all buffers referenced in the TFM context. | 5.5 |
| 2025-02-26 | CVE-2022-49567 | Use of Uninitialized Resource vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix uninit-value in mpol_rebind_policy() mpol_set_nodemask()(mm/mempolicy.c) does not set up nodemask when pol->mode is MPOL_LOCAL. | 5.5 |
| 2025-02-26 | CVE-2022-49568 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: KVM: Don't null dereference ops->destroy A KVM device cleanup happens in either of two callbacks: 1) destroy() which is called when the VM is being destroyed; 2) release() which is called when a device fd is closed. Most KVM devices use 1) but Book3s's interrupt controller KVM devices (XICS, XIVE, XIVE-native) use 2) as they need to close and reopen during the machine execution. | 5.5 |
| 2025-02-26 | CVE-2022-49569 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: spi: bcm2835: bcm2835_spi_handle_err(): fix NULL pointer deref for non DMA transfers In case a IRQ based transfer times out the bcm2835_spi_handle_err() function is called. | 5.5 |
| 2025-02-26 | CVE-2022-49571 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tcp: Fix data-races around sysctl_tcp_max_reordering. While reading sysctl_tcp_max_reordering, it can be changed concurrently. | 4.7 |
| 2025-02-26 | CVE-2022-49572 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tcp: Fix data-races around sysctl_tcp_slow_start_after_idle. While reading sysctl_tcp_slow_start_after_idle, it can be changed concurrently. | 4.7 |
| 2025-02-26 | CVE-2022-49573 | Race Condition vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tcp: Fix a data-race around sysctl_tcp_early_retrans. While reading sysctl_tcp_early_retrans, it can be changed concurrently. Thus, we need to add READ_ONCE() to its reader. | 4.7 |
