The epoll implementation in the Linux kernel 2.6.37.2 and earlier does not properly traverse a tree of epoll file descriptors, which allows local users to cause a denial of service via a crafted application that makes epoll_create and epoll_ctl system calls.Buffer overflow in the xfs_readlink function in fs/xfs/xfs_vnodeops.c in XFS in the Linux kernel 2.6, when CONFIG_XFS_DEBUG is disabled, allo ...

The skb_gro_header_slow function in include/linux/netdevice.h in the Linux kernel before 2.6.39.4, when Generic Receive Offload is enabled, resets certain fields in incorrect situations, which allows remote attackers to cause a denial of service via crafted network traffic. Race condition in the ecryptfs_mount function in fs/ecryptfs/main.c in the eCryptfs subsystem in the Linux kernel before 3. ...

In binder_release_work of binder.c, there is a possible use-after-free due to improper locking. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-161151868References: N/A A flaw was found in the way the Linux kernel"s Bluetooth implement ...

In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure. A flaw was found in the Linux kernel"s implementation of BTRFS fre ...

An issue has been reported in the Linux kernel"s handling of raw sockets. This issue can be used locally to cause denial of service or local privilege escalation from unprivileged processes or from containers with the CAP_NET_RAW capability enabled.

A NULL pointer dereference flaw was found in the Linux kernel"s SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option protocol"s category bitmap into the SELinux extensible bitmap via the" ebitmap_netlbl_import" routine. While processing the CIPSO restricted bitmap tag in the "cipso_v4_parsetag_rbm" routine, it sets the security attribute to ...

An issue where a provided address with access_ok is not checked was discovered in i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a Denial of Service or privilege escalation. A flaw was found in the prctl function, where it can ...

In the Linux kernel 5.0.21, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call.In the Linux kernel 5.4.0-rc2, there is a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c .A flaw was found in the Lin ...

A NULL pointer dereference flaw was found in the Linux kernel"s SELinux subsystem. This flaw occurs while importing the Commercial IP Security Option protocol"s category bitmap into the SELinux extensible bitmap via the" ebitmap_netlbl_import" routine. While processing the CIPSO restricted bitmap tag in the "cipso_v4_parsetag_rbm" routine, it sets the security attribute to indicate that the categ ...

There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common function in drivers/tty/n_tty.c. A flaw was found in the way KVM hypervisor handled instruction emulation for the L2 guest when nested virtualization is enabled. In the instruction emulation, the L2 guest could trick the L0 hypervisor into accessing sensitive bits of the L1 hypervisor. An L2 g ...
