CVE-2023-51043

A flaw was found in the Linux kernel Direct Rendering Infrastructure DRI subsystem in which a use-after-free can be caused when a user triggers a race condition between a nonblocking atomic commit and a driver unload. A local user could use this flaw to crash the system or potentially escalate...

kernel: tun: bugs for oversize packet when napi frags enabled in tun_napi_alloc_frags

An out-of-bounds memory access flaw was found in the Linux kernel’s TUN/TAP device driver functionality in how a user generates a malicious too big networking packet when napi frags is enabled. This flaw allows a local user to crash or potentially escalate their privileges on the system...

kernel: netfilter: potential slab-out-of-bound access due to integer underflow

An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the h-nets array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local...

kernel: Slab-out-of-bound read in compare_netdev_and_ip

A vulnerability was found in comparenetdevandip in drivers/infiniband/core/cma.c in RDMA in the Linux kernel. An improper cleanup results in an out-of-boundary read. This flaw allows a local user to crash or escalate privileges on the system...

rpm: checks for unsafe symlinks are not performed for intermediary directories

It was found that the fix for CVE-2017-7500 and CVE-2017-7501 was incomplete: the check was only implemented for the parent directory of the file to be created. A local unprivileged user who owns another ancestor directory could potentially use this flaw to gain root privileges. The highest threa...

kernel: Slab-out-of-bound read in compare_netdev_and_ip

A vulnerability was found in comparenetdevandip in drivers/infiniband/core/cma.c in RDMA in the Linux kernel. An improper cleanup results in an out-of-boundary read. This flaw allows a local user to crash or escalate privileges on the system...

kernel: use after free in vcs_read in drivers/tty/vt/vc_screen.c due to race

A use-after-free flaw was found in vcsread in drivers/tty/vt/vcscreen.c in vcscreen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information...

hw: intel: Protection mechanism failure for some Intel(R) PROSet/Wireless WiFi

Protection mechanism failure for some IntelR PROSet/Wireless WiFi software may allow a privileged user to enable escalation of privilege via local access...

kernel: igmp: use-after-free in ip_check_mc_rcu when opening and closing inet sockets

A use-after-free flaw was found in the Linux kernel’s IGMP protocol in how a user triggers a race condition in the ipcheckmcrcu function. This flaw allows a local user to crash or potentially escalate their privileges on the system...

kernel: ext4: use-after-free in ext4_xattr_set_entry()

A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the extra inode size for extended attributes. This flaw allows a privileged local user to cause a system crash or other undefined behaviors...

kernel: memory corruption in usbmon driver

An out-of-bounds memory write flaw in the Linux kernel’s USB Monitor component was found in how a user with access to the /dev/usbmon can trigger it by an incorrect write to the memory of the usbmon. This flaw allows a local user to crash or potentially escalate their privileges on the system...

kernel: use after free in vcs_read in drivers/tty/vt/vc_screen.c due to race

A use-after-free flaw was found in vcsread in drivers/tty/vt/vcscreen.c in vcscreen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information...

kernel: out-of-bounds write in qfq_change_class function

An out-of-bounds memory access flaw was found in the Linux kernel’s traffic control QoS subsystem in how a user triggers the qfqchangeclass function with an incorrect MTU value of the network device used as lmax. This flaw allows a local user to crash or potentially escalate their privileges on t...

kernel: tun: bugs for oversize packet when napi frags enabled in tun_napi_alloc_frags

An out-of-bounds memory access flaw was found in the Linux kernel’s TUN/TAP device driver functionality in how a user generates a malicious too big networking packet when napi frags is enabled. This flaw allows a local user to crash or potentially escalate their privileges on the system...

kernel: swiotlb information leak with DMA_FROM_DEVICE

A memory leak flaw was found in the Linux kernel’s DMA subsystem, in the way a user calls DMAFROMDEVICE. This flaw allows a local user to read random memory from the kernel space...
