In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix peer HE MCS assignment
In ath11k_wmi_send_peer_assoc_cmd(), peer's transmit MCS is sent to
firmware as receive MCS while peer's receive MCS sent as transmit MCS,
which goes against firmwire's definition.
While connecting to a misbehaved AP that advertises 0xffff (meaning not
supported) for 160 MHz transmit MCS map, firmware crashes due to 0xffff
is assigned to he_mcs->rx_mcs_set field.
Ext Tag: HE Capabilities
[...]
Supported HE-MCS and NSS Set
[...]
Rx and Tx MCS Maps 160 MHz
[...]
Tx HE-MCS Map 160 MHz: 0xffff
Swap the assignment to fix this issue.
As the HE rate control mask is meant to limit our own transmit MCS, it
needs to go via he_mcs->rx_mcs_set field. With the aforementioned swapping
done, change is needed as well to apply it to the peer's receive MCS.

Qualys discovered that several vulnerabilities existed in the AppArmor
Linux kernel Security Module (LSM). An unprivileged local attacker could
use these issues to load, replace, and remove arbitrary AppArmor profiles
causing denial of service, exposure of sensitive information (kernel
memory), local privilege escalation, or possibly escape a container.

It was discovered that some AMD Zen 5 processors supporting RDSEED
instruction did not properly handle entropy, potentially resulting in the
consumption of insufficiently random values. A local attacker could
possibly use this issue to influence the values returned by the RDSEED
instruction causing loss of confidentiality and integrity. (CVE-2025-62626)
