CVE-2023-33203 MED 6.4 linux linux_kernel 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. 0.4%
CVE-2023-31081 MED 5.5 linux linux_kernel An issue was discovered in drivers/media/test-drivers/vidtv/vidtv_bridge.c in the Linux kernel 6.2. There is a NULL pointer dereference in vidtv_mux_stop_thread. In vidtv_stop_streaming, after dvb->mux=NULL occurs, it executes vidtv_mux_stop_thread(dvb->mux). 0.4%
CVE-2022-0500 HIGH 7.8 fedoraproject fedora A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds memory write in the Linux kernel’s BPF subsystem due to the way a user loads BTF. This flaw allows a local user to crash or escalate their privileges on the sy 0.4%
CVE-2015-4176 MED 5.5 linux linux_kernel fs/namespace.c in the Linux kernel before 4.0.2 does not properly support mount connectivity, which allows local users to read arbitrary files by leveraging user-namespace root access for deletion of a file or directory. 0.4%
CVE-2013-4343 MED 6.9 canonical ubuntu_linux Use-after-free vulnerability in drivers/net/tun.c in the Linux kernel through 3.11.1 allows local users to gain privileges by leveraging the CAP_NET_ADMIN capability and providing an invalid tuntap interface name in a TUNSETIFF ioctl call. 0.4%
CVE-2026-53002 CRIT 9.8 linux linux_kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: remove sprintf usage Replace it with scnprintf, the buffer sizes are expected to be large enough to hold the result, no need for snprintf+overflow check. Increase buff 0.4%
