Linux kernel vulnerabilities: exploited CVEs and our analysis

Kernel

Linux Kernel contains an out-of-bounds write vulnerability in the ebtables SNAT target which allows an ARP sender hardware address rewrite to write directly into a nonlinear socket-buffer fragment backed by a splice-i…

Kernel

Linux Kernel contains a race condition vulnerability which allows concurrent writes to the same AF_ALG socket causing data to be unpredictably interleaved and creating inconsistencies in the socket's internal state.

Kernel

Linux Kernel contains an improper check for unusual or exceptional conditions vulnerability in the TLS receive path which allows a zero-length record retrieved from the rx_list to bypass the intended recvmsg() record-…

Kernel

Linux Kernel contains an unspecified vulnerability that can allow for privilege escalation via IPv6 networking subsystem. This vulnerability can impact multiple products, including but not limited to Suse, Red Hat, an…

Kernel

Linux Kernel contains an out-of-bounds memory write vulnerability which could allow a local user to gain privileged access or cause a denial of service on the system.

Kernel

Linux Kernel contains an improper authentication vulnerability which could allow for privilege escalation via the cgroups v1 release_agent feature.

Kernel

Linux Kernel contains an incorrect resource transfer between spheres vulnerability that could allow for privilege escalation.

Kernel

Linux Kernel contains an integer overflow vulnerability in the create_elf_tables() function which could allow an unprivileged local user with access to SUID (or otherwise privileged) binary to escalate their privilege…

Kernel

Linux Kernel contains a heap out-of-bounds write vulnerability that could allow an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space.

Kernel

Linux kernel contains a time-of-check time-of-use (TOCTOU) race condition vulnerability that has a high impact on confidentiality, integrity, and availability.

Kernel

Linux Kernel contains an improper ownership management vulnerability, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user c…

Kernel

Linux Kernel contains an out-of-bounds access vulnerability in the USB-audio driver that allows an attacker with physical access to the system to use a malicious USB device to potentially manipulate system memory, esc…

Kernel

Linux Kernel contains an out-of-bounds read vulnerability in the USB-audio driver that allows a local, privileged attacker to obtain potentially sensitive information.

Kernel

The Linux kernel contains a use of uninitialized resource vulnerability that allows an attacker to leak kernel memory via a specially crafted HID report.

Kernel

Linux kernel contains an out-of-bounds write vulnerability in the uvc_parse_streaming component of the USB Video Class (UVC) driver that could allow for physical escalation of privilege.

Kernel

Linux kernel contains a position-independent executable (PIE) stack buffer corruption vulnerability in load_elf_ binary() that allows a local attacker to escalate privileges.

Kernel

Linux kernel contains a heap-based buffer overflow vulnerability in the legacy_parse_param function in the Filesystem Context functionality. This allows an attacker to open a filesystem that does not support the Files…

Kernel

Linux Kernel contains a use-after-free vulnerability in the nft_object, allowing local attackers to escalate privileges.

Kernel

Linux kernel contains a use-after-free vulnerability in the netfilter: nf_tables component that allows an attacker to achieve local privilege escalation.

Kernel

Linux Kernel contains a race condition vulnerability within the n_tty_write function that allows local users to cause a denial-of-service (DoS) or gain privileges via read and write operations with long strings.

Kernel

Linux Kernel contains an improper input validation vulnerability in the Reliable Datagram Sockets (RDS) protocol implementation that allows local users to gain privileges via crafted use of the sendmsg and recvmsg sys…

Kernel

Linux kernel contains a use-after-free vulnerability that allows for privilege escalation to gain ring0 access from the system user.

Kernel

The overlayfs stacking file system in Linux kernel does not properly validate the application of file capabilities against user namespaces, which could lead to privilege escalation.

Kernel

The get_user and put_user API functions of the Linux kernel fail to validate the target address when being used on ARM v6k/v7 platforms. This allows an application to read and write kernel memory which could lead to p…

Kernel

Linux kernel fb_mmap function in drivers/video/fbmem.c contains an integer overflow vulnerability that allows for privilege escalation.

Kernel

Linux kernel fails to check all 64 bits of attr.config passed by user space, resulting to out-of-bounds access of the perf_swevent_enabled array in sw_perf_event_destroy(). Explotation allows for privilege escalation.

Kernel

The futex_requeue function in kernel/futex.c in Linux kernel does not ensure that calls have two different futex addresses, which allows local users to gain privileges.

Kernel

Linux kernel contains an improper initialization vulnerability where an unprivileged local user could escalate their privileges on the system. This vulnerability has the moniker of "Dirty Pipe."

Kernel

Linux Kernel contains a flaw in the packet socket (AF_PACKET) implementation which could lead to incorrectly freeing memory. A local user could exploit this for denial-of-service (DoS) or possibly for privilege escala…

Kernel

Race condition in mm/gup.c in the Linux kernel allows local users to escalate privileges.

Kernel

Kernel/ptrace.c in Linux kernel mishandles contains an improper privilege management vulnerability that allows local users to obtain root access.
