CVSS: 7.8EPSS: 0%CPEs: 24EXPL: 2CVE-2022-1679 – kernel: use-after-free in ath9k_htc_probe_device() could cause an escalation of privileges
https://notcve.org/view.php?id=CVE-2022-1679
A use-after-free flaw was found in the Linux kernel’s Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se ha encontrado un fallo de uso de memoria previamente liberada en el controlador del adaptador inalámbrico Atheros del kernel de Linux en la forma en que un usuario fuerza la función ath9k_htc_wait_for_target a fallar con algunos mensajes de entrada. Este fallo permite a un usuario local bloquear o escalar potencialmente sus privilegios en el sistema • https://github.com/EkamSinghWalia/-Detection-and-Mitigation-for-CVE-2022-1679 https://github.com/ov3rwatch/Detection-and-Mitigation-for-CVE-2022-1679 https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://lore.kernel.org/lkml/87ilqc7jv9.fsf%40kernel.org/t https://security.netapp.com/advisory/ntap-20220629-0007 https://access.redhat.com/security/cve/CVE-2022-1679 https://bugzilla.redhat.com/show_bug • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 2CVE-2022-1158 – kernel: KVM: cmpxchg_gpte can write to pfns outside the userspace region
https://notcve.org/view.php?id=CVE-2022-1158
A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and potentially corrupt the kernel, resulting in a denial of service condition. Se ha encontrado un fallo en KVM. Cuando era actualizada la entrada de la tabla de páginas de un huésped, vm_pgoff era usado incorrectamente como desplazamiento para obtener el pfn de la página. • https://bugzilla.redhat.com/show_bug.cgi?id=2069793 https://security.netapp.com/advisory/ntap-20230214-0003 https://www.openwall.com/lists/oss-security/2022/04/08/4 https://access.redhat.com/security/cve/CVE-2022-1158 • CWE-416: Use After Free •
