A NULL pointer dereference was found in io_file_bitmap_get in io_uring/filetable.c in the io_uring sub-component in the Linux Kernel. When fixed files are unregistered, some context information (file_alloc_{start,end} and alloc_hint) is not cleared. A subsequent request that has auto index selection enabled via IORING_FILE_INDEX_ALLOC can cause a NULL pointer dereference. An unprivileged user can use the flaw to cause a system crash. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=02a4d923e4400a36d340ea12d8058f69ebf3a383 https://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux-block.git/commit/?h=io_uring-6.3&id=761efd55a0227aca3a69deacdaa112fffd44fe37 • CWE-476: NULL Pointer Dereference •

An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event. Se descubrió un problema en el kernel de Linux hasta la versión 6.0.10. En drivers/media/dvb-core/dvb_ca_en50221.c, puede ocurrir un use-after-free si hay una desconexión después de una apertura, debido a la falta de un wait_event. A race condition flaw leading to a use-after-free issue was found in the Linux kernel media subsystem in the DVB CA EN50221 interface of the DVB core device driver. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=280a8ab81733da8bc442253c700a52c4c0886ffd https://lore.kernel.org/linux-media/20221121063308.GA33821%40ubuntu/T/#u https://security.netapp.com/advisory/ntap-20230113-0008 https://access.redhat.com/security/cve/CVE-2022-45919 https://bugzilla.redhat.com/show_bug.cgi?id=2151956 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2022-45886
An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a .disconnect versus dvb_device_open race condition that leads to a use-after-free. Se descubrió un problema en el kernel de Linux hasta la versión 6.0.9. drivers/media/dvb-core/dvb_net.c tiene una condición de carrera .disconnect versus dvb_device_open que conduce a un use-after-free. A race condition flaw leading to a use-after-free issue was found in the Linux kernel media subsystem in the dvb_net component of the DVB core device driver. It could occur between the time the device is disconnected (.disconnect function) and the time the device node is opened (dvb_device_open function). A local user could use this flaw to crash the system or potentially escalate their privileges on the system. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4172385b0c9ac366dcab78eda48c26814b87ed1a https://lore.kernel.org/linux-media/20221115131822.6640-1-imv4bel%40gmail.com https://lore.kernel.org/linux-media/20221115131822.6640-3-imv4bel%40gmail.com https://security.netapp.com/advisory/ntap-20230113-0006 https://access.redhat.com/security/cve/CVE-2022-45886 https://bugzilla.redhat.com/show_bug.cgi?id=2148517 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVSS: 6.7EPSS: 0%CPEs: 1EXPL: 0CVE-2022-2785 – Arbitrary Memory read in BPF Linux Kernel
https://notcve.org/view.php?id=CVE-2022-2785
There exists an arbitrary memory read within the Linux Kernel BPF - Constants provided to fill pointers in structs passed in to bpf_sys_bpf are not verified and can point anywhere, including memory not owned by BPF. An attacker with CAP_BPF can arbitrarily read memory from anywhere on the system. We recommend upgrading past commit 86f44fcec22c Se presenta una lectura de memoria arbitraria dentro del BPF del Kernel de Linux - Las constantes proporcionadas para rellenar los punteros en los structs pasados a bpf_sys_bpf no son verificados y pueden apuntar a cualquier lugar, incluyendo la memoria que no es propiedad de BPF. Un atacante con CAP_BPF puede leer arbitrariamente la memoria de cualquier parte del sistema.
