| 2025-02-26 | CVE-2022-49152 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: XArray: Fix xas_create_range() when multi-order entry present If there is already an entry present that is of order >= XA_CHUNK_SHIFT when we call xas_create_range(), xas_create_range() will misinterpret that entry as a node and dereference xa_node->parent, generally leading to a crash that looks something like this: general protection fault, probably for non-canonical address 0xdffffc0000000001: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f] CPU: 0 PID: 32 Comm: khugepaged Not tainted 5.17.0-rc8-syzkaller-00003-g56e337f2cf13 #0 RIP: 0010:xa_parent_locked include/linux/xarray.h:1207 [inline] RIP: 0010:xas_create_range+0x2d9/0x6e0 lib/xarray.c:725 It's deterministically reproducable once you know what the problem is, but producing it in a live kernel requires khugepaged to hit a race. While the problem has been present since xas_create_range() was introduced, I'm not aware of a way to hit it before the page cache was converted to use multi-index entries. | 4.7 |
| 2025-02-26 | CVE-2022-49155 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Suppress a kernel complaint in qla_create_qpair() [ 12.323788] BUG: using smp_processor_id() in preemptible [00000000] code: systemd-udevd/1020 [ 12.332297] caller is qla2xxx_create_qpair+0x32a/0x5d0 [qla2xxx] [ 12.338417] CPU: 7 PID: 1020 Comm: systemd-udevd Tainted: G I --------- --- 5.14.0-29.el9.x86_64 #1 [ 12.348827] Hardware name: Dell Inc. | 5.5 |
| 2025-02-26 | CVE-2022-49177 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: hwrng: cavium - fix NULL but dereferenced coccicheck error Fix following coccicheck warning: ./drivers/char/hw_random/cavium-rng-vf.c:182:17-20: ERROR: pdev is NULL but dereferenced. | 5.5 |
| 2025-02-26 | CVE-2022-49185 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: pinctrl: nomadik: Add missing of_node_put() in nmk_pinctrl_probe This node pointer is returned by of_parse_phandle() with refcount incremented in this function. | 5.5 |
| 2025-02-26 | CVE-2022-49190 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: kernel/resource: fix kfree() of bootmem memory again Since commit ebff7d8f270d ("mem hotunplug: fix kfree() of bootmem memory"), we could get a resource allocated during boot via alloc_resource(). | 5.5 |
| 2025-02-26 | CVE-2022-49201 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ibmvnic: fix race between xmit and reset There is a race between reset and the transmit paths that can lead to ibmvnic_xmit() accessing an scrq after it has been freed in the reset path. | 4.7 |
| 2025-02-26 | CVE-2022-49206 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix memory leak in error flow for subscribe event routine In case the second xa_insert() fails, the obj_event is not released. | 5.5 |
| 2025-02-26 | CVE-2022-49209 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix memleak in tcp_bpf_sendmsg while sk msg is full If tcp_bpf_sendmsg() is running while sk msg is full. | 5.5 |
| 2025-02-26 | CVE-2022-49212 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: atmel: fix refcount issue in atmel_nand_controller_init The reference counting issue happens in several error handling paths on a refcounted object "nc->dmac". | 5.5 |
| 2025-02-26 | CVE-2022-49215 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: xsk: Fix race at socket teardown Fix a race in the xsk socket teardown code that can lead to a NULL pointer dereference splat. | 4.7 |
