A use-after-free in the network scheduler due to a race problem. This flaw leads to a denial of service issue.

A NULL pointer dereference in traffic control. This issue may allow a local unprivileged user to trigger a system crash or leaked internal kernel information.

A NULL pointer dereference in the netfilter subsystem. This flaw allows a local, unprivileged user to crash the system, resulting in a denial of service.

A use-after-free flaw in vc_screen. This flaw allows an attacker with local user access to cause a system crash or leak internal kernel information.

A flaw in the TC flower classifier (cls_flower) in the Networking subsystem. This issue occurs when sending two TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets with a total size of 252 bytes, which results in an out-of-bounds write, potentially leading to a denial of service or privilege escalation.

An out-of-bounds memory write flaw in the Traffic Control (QoS) subsystem. This flaw allows a local user to crash or potentially escalate their privileges on the system.

A flaw in the IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to cause kernel crash and denial of service.

A use-after-free vulnerability in a network scheduler sub-component. This may allow a local attacker to gain local privilege escalation.

A double-free flaw in the Network Scheduler component. This flaw allows a local attacker to use a failure event to mishandle the reference counter, leading to a local privilege escalation threat.

A NULL pointer dereference in the UDF file system functionality. This flaw allows a local user to crash the system.

A use-after-free flaw in the IGMP protocol. This flaw allows a local user to crash or potentially escalate their privileges on the system.

Partial fix to prevent memory leak in some cases.

Possible deadlock in kernel during connect to cluster storage.

Unstable network connection caused by corruption packets in the network card driver.

Possible kernel crash while handling out of memory situation.

An attacker could use prepared image to crash the system or leak internal kernel information.

Hooks collision during nftables and iptables hooks registering.

A memory leak in Changed Block Tracking code.

There is a possible deadlock if a lazytime-enabled mounted ploop is running on top of vStorage. This tweak provides the ability to disable default lazytime mount option for ext4 mounts. For technical reasons this tweak is united with the oom_dump_tasks sysctl. You should use this sysctl in the following way: "echo 0 > /proc/sys/vm/oom_dump_tasks" - disable lazytime default and oom tasks dumping; "echo 1 > /proc/sys/vm/oom_dump_tasks" - disable lazytime default, enable oom tasks dumping; "echo 2 > /proc/sys/vm/oom_dump_tasks" - enable lazytime default, disable oom tasks dumping; "echo 3 > /proc/sys/vm/oom_dump_tasks" - enable lazytime default and oom tasks dumping.

NULL pointer accsess in nf_tables chain filter leads to node crash.

Avoid possible deadlock and packet loss. Fixes: PSBM-140896 Potential ARP DoS.

A data leak flaw was found in XFS filesystem. An attacker could use this flaw to read deleted data.

use-after-free flaw was found in the Linux kernel’s vmw_execbuf_copy_fence_user function in vmwgfx. This flaw allows a local attacker with user privileges to cause a privilege escalation problem.

Incorrect GPU cache flush may allow access to system memory and run malicious code on GPU.

There is double dput in nfs_prime_dcache(). Because of this excess dput we get a crash in __put_nfs_open_context().

The bug allows to initialize a non-stateful lookup expressions which points to a not properly detached set, which might lead to UAF. Potetntially it leads to privilege escalation.

Setting release_agent could potentially lead to privilege escalation from unprivileged users inside a container to the container root. It couldn't be exploited to escape containers.

Race condition between the garbage collector and the 'recv' operation with MSG_PEEK flag was found in the implementation of UNIX domain sockets. It could result in use-after-free and could potentially allow a local attacker to escalate their privileges in the system.
