https://notcve.org/view.php?id=CVE-2022-0492
A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly. Se ha encontrado una vulnerabilidad en la función cgroup_release_agent_write en el archivo kernel/cgroup/cgroup-v1.c del kernel de Linux. Este fallo, bajo determinadas circunstancias, permite el uso de la función cgroups v1 release_agent para escalar privilegios y saltarse el aislamiento del espacio de nombres de forma no esperada • https://github.com/chenaotian/CVE-2022-0492 https://github.com/SofianeHamlaoui/CVE-2022-0492-Checker https://github.com/yoeelingBin/CVE-2022-0492-Container-Escape https://github.com/T1erno/CVE-2022-0492-Docker-Breakout-Checker-and-PoC https://github.com/bb33bb/CVE-2022-0492 http://packetstormsecurity.com/files/166444/Kernel-Live-Patch-Security-Notice-LSN-0085-1.html http://packetstormsecurity.com/files/167386/Kernel-Live-Patch-Security-Notice-LSN-0086-1.html http://packetstormsecurity.com/files/17 • CWE-287: Improper Authentication CWE-862: Missing Authorization •
CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 5CVE-2022-25636 – kernel: heap out of bounds write in nf_dup_netdev.c
https://notcve.org/view.php?id=CVE-2022-25636
net/netfilter/nf_dup_netdev.c in the Linux kernel 5.4 through 5.6.10 allows local users to gain privileges because of a heap out-of-bounds write. This is related to nf_tables_offload. El archivo net/netfilter/nf_dup_netdev.c en el kernel de Linux versiones 5.4 hasta 5.6.10, permite a usuarios locales alcanzar privilegios debido a una escritura fuera de los límites de la pila. Esto está relacionado con nf_tables_offload An out-of-bounds (OOB) memory access flaw was found in nft_fwd_dup_netdev_offload in net/netfilter/nf_dup_netdev.c in the netfilter subcomponent in the Linux kernel due to a heap out-of-bounds write problem. This flaw allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a privilege escalation threat. • https://github.com/Bonfee/CVE-2022-25636 https://github.com/veritas501/CVE-2022-25636-PipeVersion https://github.com/chenaotian/CVE-2022-25636 http://packetstormsecurity.com/files/166444/Kernel-Live-Patch-Security-Notice-LSN-0085-1.html http://www.openwall.com/lists/oss-security/2022/02/22/1 https://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf.git/commit/?id=b1a5983f56e371046dcf164f90bfaf704d2b89f6 https://nickgregory.me/linux/security/2022/03/12/cve-2022-25636 https://security • CWE-269: Improper Privilege Management CWE-787: Out-of-bounds Write •
