CVSS: 6.7EPSS: 0%CPEs: 1EXPL: 1CVE-2020-36694 – kernel: netfilter: use-after-free in the packet processing context
https://notcve.org/view.php?id=CVE-2020-36694
21 May 2023 — An issue was discovered in netfilter in the Linux kernel before 5.10. There can be a use-after-free in the packet processing context, because the per-CPU sequence count is mishandled during concurrent iptables rules replacement. This could be exploited with the CAP_NET_ADMIN capability in an unprivileged namespace. NOTE: cc00bca was reverted in 5.12. A use-after-free flaw was found in the packet processing context in net/netfilter/x_tables.c in netfilter in the Linux Kernel. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.10 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-33203
18 May 2023 — The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based device. A race condition vulnerability was found in the Linux kernel's Qualcomm EMAC Gigabit Ethernet Controller when the user physically removes the device before cleanup in the emac_remove function. This flaw can eventually result in a use-after-free issue, possibly leading to a system crash or other undefined behaviors. • https://bugzilla.redhat.com/show_bug.cgi?id=2192667 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
