| 2024-05-17 | CVE-2023-52698 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: calipso: fix memory leak in netlbl_calipso_add_pass() If IPv6 support is disabled at boot (ipv6.disable=1), the calipso_init() -> netlbl_calipso_ops_register() function isn't called, and the netlbl_calipso_ops_get() function always returns NULL. In this case, the netlbl_calipso_add_pass() function allocates memory for the doi_def variable but doesn't free it with the calipso_doi_free(). BUG: memory leak unreferenced object 0xffff888011d68180 (size 64): comm "syz-executor.1", pid 10746, jiffies 4295410986 (age 17.928s) hex dump (first 32 bytes): 00 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<...>] kmalloc include/linux/slab.h:552 [inline] [<...>] netlbl_calipso_add_pass net/netlabel/netlabel_calipso.c:76 [inline] [<...>] netlbl_calipso_add+0x22e/0x4f0 net/netlabel/netlabel_calipso.c:111 [<...>] genl_family_rcv_msg_doit+0x22f/0x330 net/netlink/genetlink.c:739 [<...>] genl_family_rcv_msg net/netlink/genetlink.c:783 [inline] [<...>] genl_rcv_msg+0x341/0x5a0 net/netlink/genetlink.c:800 [<...>] netlink_rcv_skb+0x14d/0x440 net/netlink/af_netlink.c:2515 [<...>] genl_rcv+0x29/0x40 net/netlink/genetlink.c:811 [<...>] netlink_unicast_kernel net/netlink/af_netlink.c:1313 [inline] [<...>] netlink_unicast+0x54b/0x800 net/netlink/af_netlink.c:1339 [<...>] netlink_sendmsg+0x90a/0xdf0 net/netlink/af_netlink.c:1934 [<...>] sock_sendmsg_nosec net/socket.c:651 [inline] [<...>] sock_sendmsg+0x157/0x190 net/socket.c:671 [<...>] ____sys_sendmsg+0x712/0x870 net/socket.c:2342 [<...>] ___sys_sendmsg+0xf8/0x170 net/socket.c:2396 [<...>] __sys_sendmsg+0xea/0x1b0 net/socket.c:2429 [<...>] do_syscall_64+0x30/0x40 arch/x86/entry/common.c:46 [<...>] entry_SYSCALL_64_after_hwframe+0x61/0xc6 Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with Syzkaller [PM: merged via the LSM tree at Jakub Kicinski request] | 5.5 |
| 2024-05-17 | CVE-2024-35846 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm: zswap: fix shrinker NULL crash with cgroup_disable=memory Christian reports a NULL deref in zswap that he bisected down to the zswap shrinker. | 5.5 |
| 2024-05-17 | CVE-2024-35850 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: qca: fix NULL-deref on non-serdev setup Qualcomm ROME controllers can be registered from the Bluetooth line discipline and in this case the HCI UART serdev pointer is NULL. Add the missing sanity check to prevent a NULL-pointer dereference when setup() is called for a non-serdev controller. | 5.5 |
| 2024-05-17 | CVE-2024-35851 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: qca: fix NULL-deref on non-serdev suspend Qualcomm ROME controllers can be registered from the Bluetooth line discipline and in this case the HCI UART serdev pointer is NULL. Add the missing sanity check to prevent a NULL-pointer dereference when wakeup() is called for a non-serdev controller during suspend. Just return true for now to restore the original behaviour and address the crash with pre-6.2 kernels, which do not have commit e9b3e5b8c657 ("Bluetooth: hci_qca: only assign wakeup with serial port support") that causes the crash to happen already at setup() time. | 5.5 |
| 2024-05-17 | CVE-2024-35852 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_tcam: Fix memory leak when canceling rehash work The rehash delayed work is rescheduled with a delay if the number of credits at end of the work is not negative as supposedly it means that the migration ended. | 5.5 |
| 2024-05-17 | CVE-2024-35858 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: fix memory leak when bringing down interface When bringing down the TX rings we flush the rings but forget to reclaimed the flushed packets. | 5.5 |
| 2024-05-17 | CVE-2023-52662 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: fix a memleak in vmw_gmrid_man_get_node When ida_alloc_max fails, resources allocated before should be freed, including *res allocated by kmalloc and ttm_resource_init. | 5.5 |
| 2024-05-17 | CVE-2023-52663 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: amd: Fix memory leak in amd_sof_acp_probe() Driver uses kasprintf() to initialize fw_{code,data}_bin members of struct acp_dev_data, but kfree() is never called to deallocate the memory, which results in a memory leak. Fix the issue by switching to devm_kasprintf(). | 5.5 |
| 2024-05-17 | CVE-2024-35795 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix deadlock while reading mqd from debugfs An errant disk backup on my desktop got into debugfs and triggered the following deadlock scenario in the amdgpu debugfs files. | 5.5 |
| 2024-05-17 | CVE-2024-35806 | Improper Locking vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: soc: fsl: qbman: Always disable interrupts when taking cgr_lock smp_call_function_single disables IRQs when executing the callback. | 5.5 |
