CVE-2024-50119

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cifs: se corrige la advertencia al destruir 'cifs_io_request_pool' Hay un problema como el siguiente: ADVERTENCIA: CPU: 1 PID: 27826 en mm/slub.c:4698 free_large_kmalloc+0xac/0xe0 RIP: 0010:free_large_kmalloc+0xac/0xe0 Rastreo de llamadas: ? Obviamente, 'cifs_io_request_pool' no es creado por mempool_create(). Entonces simplemente use mempool_exit() para revertir 'cifs_io_request_pool'.

In the Linux kernel, the following vulnerability has been resolved: cifs: fix warning when destroy 'cifs_io_request_pool' There's a issue as follows: WARNING: CPU: 1 PID: 27826 at mm/slub.c:4698 free_large_kmalloc+0xac/0xe0 RIP: 0010:free_large_kmalloc+0xac/0xe0 Call Trace: <TASK> ? __warn+0xea/0x330 mempool_destroy+0x13f/0x1d0 init_cifs+0xa50/0xff0 [cifs] do_one_initcall+0xdc/0x550 do_init_module+0x22d/0x6b0 load_module+0x4e96/0x5ff0 init_module_from_file+0xcd/0x130 idempotent_init_module+0x330/0x620 __x64_sys_finit_module+0xb3/0x110 do_syscall_64+0xc1/0x1d0 entry_SYSCALL_64_after_hwframe+0x77/0x7f Obviously, 'cifs_io_request_pool' is not created by mempool_create(). So just use mempool_exit() to revert 'cifs_io_request_pool'.

Attila Szász discovered that the HFS+ file system implementation in the Linux Kernel contained a heap overflow vulnerability. An attacker could use a specially crafted file system image that, when mounted, could cause a denial of service or possibly execute arbitrary code. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
