CVE-2021-22600

CVE-2021-22600 is a local kernel vulnerability in the Linux packet migration path. A double-free in packet_set_ring() within net/packet/af_packet.c can be exploited by a local user via crafted syscalls, enabling either denial of service or privilege escalation. Connected sources confirm the under...

CVE-2020-29661

The entry CVE-2020-29661 describes a local, kernel-space vulnerability in the Linux tty subsystem (drivers/tty/tty_jobctrl.c) that can enable a use-after-free through TIOCSPGRP. A locking issue in this path allows memory corruption and potential privilege escalation or system impact when an attac...

CVE-2019-20054

CVE-2019-20054 affects the Linux kernel prior to 5.0.6, with a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c (related to put_links, CID-23da9588037e). The fix is included in kernel 5.0.6 (and later). Public exploit details are not provided in the supplied documents. Rec...

CVE-2019-5108

CVE-2019-5108 is an exploitable denial-of-service in the Linux kernel prior to mainline 5.3. An attacker can trigger IAPP location updates for stations before authentication completes by forging Authentication/Association Request packets, leading to potential CAM-table attacks or traffic flapping...

CVE-2020-29660

This CVE (CVE-2020-29660) affects the Linux kernel tty subsystem, specifically in drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c, where a locking inconsistency can enable a local attacker to perform a read-after-free against TIOCGSID. Consequences stated in multiple advisories include memory ...

CVE-2022-30594

The CVE-2022-30594 issue affects the Linux kernel prior to 5.17.2, where the PTRACE_SEIZE path could bypass the PT_SUSPEND_SECCOMP restrictions and allow a local attacker to bypass seccomp-related restrictions. Connected advisories (Astra Linux, AlmaLinux advisories) confirm the same vulnerabilit...

CVE-2019-18282

CVE-2019-18282 affects the Linux kernel flow_dissector (Linux 4.3–5.x up to 5.3.10). The root cause is that UDP/IPv6 flow labels rely on a 32-bit hashrnd secret, with jhash used instead of siphash, allowing an attacker to infer the secret and track flows. Affected code includes net/core/flow_diss...

CVE-2019-20095

CVE-2019-20095 affects the Linux kernel mwifiex driver (drivers/net/wireless/marvell/mwifiex/cfg80211.c). The description states that certain error-handling paths do not free allocated hostcmd memory, causing a memory leak that can lead to a denial of service. The issue is fixed in kernel version...

CVE-2023-1077

CVE-2023-1077A: Linux kernel scheduling: In pick_next_rt_entity(), a type confusion can occur where a non-NULL, non-entry object (a list_head) is misinterpreted as a sched_rt_entity, bypassing BUG_ON checks and causing memory corruption. Public docs (Astra Linux page) mirror this description for ...

CVE-2019-19965

CVE-2019-19965 is a vulnerability in the Linux kernel (affecting the SAS SAS discover path) where a NULL pointer dereference occurs in drivers/scsi/libsas/sas_discover.c due to mishandling of port disconnection during discovery, related to a PHY down race condition (CID-f70267f379b5). The Unity L...

CVE-2019-18683

CVE-2019-18683 affects the Linux kernel’s V4L2 vivid driver (drivers/media/platform/vivid). The issue arises from wrong mutex locking in functions vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and related kthreads, causing multiple race conditions dur...

CVE-2020-15025

The CVE-2020-15025 entry concerns ntpd (NTP) memory exhaustion via CMAC-related paths. Affected: ntpd 4.2.8 prior to 4.2.8p15 and 4.3.x prior to 4.3.101. Root cause: memory is not freed in CMAC-key scenarios in ntp.keys, enabling remote packets to trigger a denial of service through memory consum...

CVE-2020-8835

CVE-2020-8835 affects Linux kernel 5.5.0 and newer, with backports to 5.4.x. The issue is in the BPF verifier (kernel/bpf/verifier.c): it truncates 64-bit values to 32-bit for 32-bit operations, causing the verifier’s checked bounds to diverge from actual execution. This can lead to out-of-bounds...

CVE-2024-26735

CVE-2024-26735 concerns the Linux kernel IPv6 SR subsystem. The issue is a use-after-free and a null pointer dereference in the ipv6/sr path, caused by registering the pernet operations structure for the subsystem after the generic netlink family, i.e., the pernet ops are not registered in the co...

CVE-2022-0742

CVE-2022-0742: Memory leak in Linux kernel ICMPv6 implementation (Linux kernel 5.13+) can allow a remote attacker to cause a DoS by flooding with ICMPv6 packets of type 130/131, exhausting memory. The advisory references a fix via a commit: 2d3916f3189172d5c69d33065c3c21119fe539fc. Connected sour...

CVE-2024-26733

CVE-2024-26733 (Linux kernel) : A heap-based buffer overflow in arp_req_get() was fixed. The issue occurs when ioctl(SIOCGARP) copies neigh->ha into arpreq.arp_ha.sa_data (14-byte sockaddr) with a 14-byte copy, risking overflow into arp_flags and overwriting arp_netmask if dev->addr_len exc...
