CVE-2022-2964 – kernel: memory corruption in AX88179_178A based USB ethernet device.
https://notcve.org/view.php?id=CVE-2022-2964
A flaw was found in the Linux kernel’s driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes. Se ha encontrado un fallo en el controlador del kernel de Linux para los dispositivos USB 2.0/3.0 Gigabit Ethernet basados en ASIX versión AX88179_178A.

CVE-2022-2639 – kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size()
https://notcve.org/view.php?id=CVE-2022-2639
An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se ha encontrado un error de coerción de enteros en el módulo del kernel openvswitch. Dado un número suficientemente grande de acciones, mientras ses copiado y es reservada memoria para una nueva acción de un nuevo flujo, la función reserve_sfa_size() no devuelve -EMSGSIZE como es esperado, conllevando potencialmente a un acceso de escritura fuera de límites. • https://github.com/bb33bb/CVE-2022-2639-PipeVersion https://github.com/letsr00t/-2022-LOCALROOT-CVE-2022-2639 https://github.com/EkamSinghWalia/Detection-and-Mitigation-for-CVE-2022-2639 https://bugzilla.redhat.com/show_bug.cgi?id=2084479 https://github.com/torvalds/linux/commit/cefa91b2332d7009bc0be5d951d6cbbf349f90f8 https://access.redhat.com/security/cve/CVE-2022-2639 • CWE-192: Integer Coercion Error CWE-681: Incorrect Conversion between Numeric Types •
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-2022-1355 – libtiff: stack-buffer-overflow in tiffcp.c in main()
https://notcve.org/view.php?id=CVE-2022-1355
A stack buffer overflow flaw was found in Libtiffs' tiffcp.c in main() function. This flaw allows an attacker to pass a crafted TIFF file to the tiffcp tool, triggering a stack buffer overflow issue, possibly corrupting the memory, and causing a crash that leads to a denial of service.
