CVE-2022-2153 – kernel: KVM: NULL pointer dereference in kvm_irq_delivery_to_apic_fast()
https://notcve.org/view.php?id=CVE-2022-2153
A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service. Se ha encontrado un fallo en el KVM del kernel de Linux cuando es intentado establecer una IRQ SynIC. Este problema hace posible a un VMM que sea comportado inapropiadamente escribir en las MSR de SYNIC/STIMER, causando una desreferencia de puntero NULL. • https://bugzilla.redhat.com/show_bug.cgi?id=2069736 https://github.com/torvalds/linux/commit/00b5f37189d24ac3ed46cb7f11742094778c46ce https://github.com/torvalds/linux/commit/7ec37d1cbe17d8189d9562178d8b29167fe1c31a https://github.com/torvalds/linux/commit/b1e34d325397a33d97d845e312d7cf2a8b646b44 https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://www.openwall.com/lists/oss-security/2022/06/22/1 https://access.redhat.com/security& • CWE-476: NULL Pointer Dereference •
CVE-2022-3028 – kernel: race condition in xfrm_probe_algs can lead to OOB read/write
https://notcve.org/view.php?id=CVE-2022-3028
A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. Se ha encontrado una condición de carrera en el marco IP del kernel de Linux para la transformación de paquetes (subsistema XFRM) cuando son producidas simultáneamente varias llamadas a xfrm_probe_algs. Este fallo podría permitir a un atacante local desencadenar potencialmente una escritura fuera de límites o una pérdida de memoria de la pila del kernel al llevar a cabo una lectura fuera de límites y copiarla en un socket • https://github.com/torvalds/linux/commit/ba953a9d89a00c078b85f4b190bc1dde66fe16b5 https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F3MYP7WX4PNE6RCITVXA43CECBZT4CL6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JKVA75UHKVOHNOEPCLUHTFGWCOOUBDM3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraprojec • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-667: Improper Locking CWE-787: Out-of-bounds Write •
CVE-2022-1354 – libtiff: heap-buffer-overflow in TIFFReadRawDataStriped() in tiffinfo.c
