https://notcve.org/view.php?id=CVE-2022-1247
An issue found in linux-kernel that leads to a race condition in rose_connect(). The rose driver uses rose_neigh->use to represent how many objects are using the rose_neigh. When a user wants to delete a rose_route via rose_ioctl(), the rose driver calls rose_del_node() and removes neighbours only if their “count” and “use” are zero. Se ha encontrado un problema en linux-kernel que conlleva a una condición de carrera en la función rose_connect(). El controlador de rose usa rose_neigh-)use para representar cuántos objetos están usando el rose_neigh. • https://access.redhat.com/security/cve/CVE-2022-1247 https://bugzilla.redhat.com/show_bug.cgi?id=2066799 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 5.5EPSS: 0%CPEs: 7EXPL: 1CVE-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 •
