Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux kernel suffers from a security vulnerability that stems from a missing attachbtf that causes a crash...

UBUNTU-CVE-2023-52438

In the Linux kernel, the following vulnerability has been resolved: binder: fix use-after-free in shinker's callback The mmap read lock is used during the shrinker's callback, which means that using alloc-vma pointer isn't safe as it can race with munmap. As of commit dd2283f2605e "mm: mmap: zap...

CVE-2023-52435 net: prevent mss overflow in skb_segment()

In the Linux kernel, the following vulnerability has been resolved: net: prevent mss overflow in skbsegment Once again syzbot is able to crash the kernel in skbsegment 1 GSOBYFRAGS is a forbidden value, but unfortunately the following computation in skbsegment can reach it quite easily : mss = ms...

CVE-2022-23089

When dumping core and saving process information, procgetargv might return an sbuf which have a sbuflen of 0 or -1, which is not properly handled. An out-of-bound read can happen when user constructs a specially crafted psstring, which in turn can cause the kernel to crash...

Out-of-bounds

When dumping core and saving process information, procgetargv might return an sbuf which have a sbuflen of 0 or -1, which is not properly handled. An out-of-bound read can happen when user constructs a specially crafted psstring, which in turn can cause the kernel to crash...

CVE-2022-23089

CVE-2022-23089 affects FreeBSD kernels where, during core dump handling, proc_getargv() can return an sbuf with sbuf_len() 0 or -1, which is not properly handled. This can enable an out-of-bounds read when a user constructs a specially crafted ps_string, potentially crashing the kernel. Documente...

CVE-2022-23089 Out of bound read in elf_note_prpsinfo()

When dumping core and saving process information, procgetargv might return an sbuf which have a sbuflen of 0 or -1, which is not properly handled. An out-of-bound read can happen when user constructs a specially crafted psstring, which in turn can cause the kernel to crash...

SUSE CVE-2024-1151

A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a recursive operation of code push recursively calls into the code block. The OVS module does not validate the stack depth, pushing too many frames and causing a stack overflow. As a result,...

kernel: use-after-free bug in remove function xgene_hwmon_remove

A use-after-free flaw was found in xgenehwmonremove in drivers/hwmon/xgene-hwmon.c in the Hardware Monitoring Linux Kernel driver xgene-hwmon. This flaw could allow a local attacker to crash the system due to a race problem, possibly leading to a kernel information leak...

kernel: Possible use-after-free since the two fdget() during vhost_net_set_backend()

A use-after-free flaw was found in vhostnetsetbackend in drivers/vhost/net.c in the virtio network subcomponent in the Linux kernel due to a double fget. This issue could allow a local attacker to crash the system, and could lead to a kernel information leak problem...

In btrfs_get_root_ref in fs/btrfs/disk-io.c in the Linux kernel through 6.7.1 there can be an assertion failure and crash because a subvolume can be read out too soon after its root item is inserted upon subvolume creation.

kernel: null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip

A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in progress to detach in sltxtimeout in drivers/net/slip/slip.c. This issue could allow an attacker to crash the system or leak internal kernel information...

CVE-2024-23851

copyparams in drivers/md/dm-ioctl.c in the Linux kernel through 6.7.1 can attempt to allocate more than INTMAX bytes, and crash, because of a missing paramkernel-datasize check. This is related to ctlioctl...
