CVSS: 7.0EPSS: 0%CPEs: 11EXPL: 0CVE-2022-45884 – kernel: use-after-free due to race condition occurring in dvb_register_device()
https://notcve.org/view.php?id=CVE-2022-45884
An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvbdev.c has a use-after-free, related to dvb_register_device dynamically allocating fops. Se descubrió un problema en el kernel de Linux hasta la versión 6.0.9. drivers/media/dvb-core/dvbdev.c tiene un use-after-free, relacionado con dvb_register_device que asigna dinámicamente fops. A race condition flaw leading to a use-after-free issue was found in the Linux kernel media subsystem in the DVB core device driver. It could occur in the dvb_register_device() function due to the file_operations structure (fops) being dynamically allocated and later kfreed. 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=627bb528b086b4136315c25d6a447a98ea9448d3 https://lore.kernel.org/linux-media/20221115131822.6640-1-imv4bel%40gmail.com https://lore.kernel.org/linux-media/20221115131822.6640-4-imv4bel%40gmail.com https://security.netapp.com/advisory/ntap-20230113-0006 https://access.redhat.com/security/cve/CVE-2022-45884 https://bugzilla.redhat.com/show_bug.cgi?id=2148510 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
