net/xfrm/xfrm_user.c in the Linux kernel before 3.6 does not verify that the actual Netlink message length is consistent with a certain header field, which allows local users to obtain sensitive information from kernel heap memory by leveraging the CAP_NET_ADM…

libata in the Linux kernel before 2.6.27.9 does not set minimum timeouts for SG_IO requests, which allows local users to cause a denial of service (Programmed I/O mode on drives) via multiple simultaneous invocations of an unspecified test program.

Unspecified vulnerability in the 32-bit and 64-bit emulation in the Linux kernel 2.6.9, 2.6.18, and probably other versions allows local users to read uninitialized memory via unknown vectors involving a crafted binary.

In the Linux kernel, the following vulnerability has been resolved: tcp: Add preempt_{disable,enable}_nested() in reqsk_queue_hash_req(). syzbot reported a weird reqsk->rsk_refcnt underflow in __inet_csk_reqsk_queue_drop(). The captured reqsk_put() in __ine…

In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate num_aces and harden ACE walk in smb_inherit_dacl() smb_inherit_dacl() trusts the on-disk num_aces value from the parent directory's DACL xattr and uses it to size a heap allo…

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtk_eth_soc: fix memory corruption during fq dma init The loop responsible for allocating up to MTK_FQ_DMA_LENGTH buffers must only touch as many descriptors, otherwise it end…

An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.

A flaw was found in the Linux kernel's freescale hypervisor manager implementation, kernel versions 5.0.x up to, excluding 5.0.17. A parameter passed to an ioctl was incorrectly validated and used in size calculations for the page size calculation. An attacker…

The print_binder_ref_olocked function in drivers/android/binder.c in the Linux kernel 4.14.90 allows local users to obtain sensitive address information by reading " ref *desc *node" lines in a debugfs file.

fs/namespace.c in the Linux kernel before 4.9 does not restrict how many mounts may exist in a mount namespace, which allows local users to cause a denial of service (memory consumption and deadlock) via MS_BIND mount system calls, as demonstrated by a loop th…

Buffer overflow in the isdn_net_setcfg function in isdn_net.c in Linux kernel 2.6.23 allows local users to have an unknown impact via a crafted argument to the isdn_ioctl function.

The ATM module in the Linux kernel before 2.4.35.3, when CLIP support is enabled, allows local users to cause a denial of service (kernel panic) by reading /proc/net/atm/arp before the CLIP module has been loaded.

The random number feature in Linux kernel 2.6 before 2.6.20.13, and 2.6.21.x before 2.6.21.4, (1) does not properly seed pools when there is no entropy, or (2) uses an incorrect cast when extracting entropy, which might cause the random number generator to pro…

ip_nat_pptp in the PPTP NAT helper (netfilter/ip_nat_helper_pptp.c) in Linux kernel 2.6.14, and other versions, allows local users to cause a denial of service (memory corruption or crash) via a crafted outbound packet that causes an incorrect offset to be cal…

Linux kernel 2.4.10 through 2.4.21-pre4 does not properly handle the O_DIRECT feature, which allows local attackers with write privileges to read portions of previously deleted files, or cause file system corruption.

In the Linux kernel, the following vulnerability has been resolved: tipc: fix double-free in tipc_buf_append() tipc_msg_validate() can potentially reallocate the skb it is validating, freeing the old one. In tipc_buf_append(), it was being called with a poi…

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix command flush on cable pull System crash due to command failed to flush back to SCSI layer. BUG: unable to handle kernel NULL pointer dereference at 0000000000000000 PG…

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Wake DMCUB before executing GPINT commands [Why] DMCUB can be in idle when we attempt to interface with the HW through the GPINT mailbox resulting in a system hang. [How] A…

In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small.

The NFSv4 implementation in the Linux kernel through 4.11.1 allows local users to cause a denial of service (resource consumption) by leveraging improper channel callback shutdown when unmounting an NFSv4 filesystem, aka a "module reference and kernel daemon" …

The do_remount function in fs/namespace.c in the Linux kernel through 3.16.1 does not maintain the MNT_LOCK_READONLY bit across a remount of a bind mount, which allows local users to bypass an intended read-only restriction and defeat certain sandbox protectio…

The tcp_read_sock function in net/ipv4/tcp.c in the Linux kernel before 2.6.34 does not properly manage skb consumption, which allows local users to cause a denial of service (system crash) via a crafted splice system call for a TCP socket.
