kernel: use-after-free in rwsem_down_write_slowpath in kernel/locking/rwsem.c

In the Linux kernel 5.3.11, mounting a crafted btrfs image twice can cause an rwsem_down_write_slowpath use-after-free because (in rwsem_can_spin_on_owner in kernel/locking/rwsem.c) rwsem_owner_flags returns an already freed pointer,

kernel: Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c allows for a DoS

Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-d10dcb615c8e.

kernel: A memory leak in the rpmsg_eptdev_write_iter() function in drivers/rpmsg/rpmsg_char.c allows attackers to cause a DoS

A memory leak in the rpmsg_eptdev_write_iter() function in drivers/rpmsg/rpmsg_char.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering copy_from_iter_full() failures, aka CID-bbe692e349e2.

kernel: dos in gs_can_open() function in drivers/net/can/usb/gs_usb.c

A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-fb5be6a7b486.

kernel: dos in crypto_reportstat() function in crypto/crypto_user_stat.c

A memory leak in the crypto_reportstat() function in crypto/crypto_user_stat.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_reportstat_alg() failures, aka CID-c03b04dcdba1.

kernel: dos in v3d_submit_cl_ioctl() function in drivers/gpu/drm/v3d/v3d_gem.c

Two memory leaks in the v3d_submit_cl_ioctl() function in drivers/gpu/drm/v3d/v3d_gem.c in the Linux kernel before 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering kcalloc() or v3d_job_init() failures, aka CID-29cd13cfd762.

kernel: integer overflow in tcp_ack_update_rtt in net/ipv4/tcp_input.c

An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6.

kernel: race condition in vivid_stop_generating_vid_cap(),vivid_stop_generating_vid_out(), sdr_cap_stop_streaming()

An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

kernel: The flow_dissector feature allows device tracking

The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.

kernel: Memory leak in hsr_dev_finalize() in net/hsr/hsr_device.c

In the Linux kernel before 5.0.3, a memory leak exits in hsr_dev_finalize() in net/hsr/hsr_device.c if hsr_add_port fails to add a port, which may cause denial of service, aka CID-6caabe7f197d.

kernel: vhost-net: guest to host kernel escape during migration

A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.

kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.

There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.

Improper input validation in the API for Intel(R) Graphics Driver versions before 26.20.100.7209 may allow an authenticated user to potentially enable denial of service via local access.

Improper access control in the API for the Intel(R) Graphics Driver versions before 26.20.100.7209 may allow an authenticated user to potentially enable information disclosure via local access.
