CVE-2026-80641

A flaw was found in the Linux kernel's wlcore Wi-Fi driver. An incorrect firmware version check for Integrity Group Temporal Key IGTK causes the number of available ciphers to continuously decrease on systems using older firmware, particularly affecting wl12xx chips. This issue leads to repeated...

CVE-2026-51689

Incorrect access control in the setUpgradeFW function of TOTOLINK T6 4.1.5cu.748B20211015 allows unauthenticated attackers to trigger firmware-upgrade workflow changes via sending a crafted POST request to /cgi-bin/cstecgi.cgi...

CVE-2026-80593

A flaw was found in the Linux kernel, specifically within the hwmon hardware monitoring subsystem's asusatk0110 driver. This vulnerability occurs because the atkecpresent function does not properly check the size of a data package before attempting to read its contents. A local attacker could...

CVE-2026-51671

Incorrect access control in the getCloudDownloadStatus function of TOTOLINK T6 4.1.5cu.748B20211015 allows unauthenticated attackers to obtain cloud firmware download state information via sending a crafted POST request to /cgi-bin/cstecgi.cgi...

CVE-2026-80706

A flaw was found in the softing module of the Linux kernel. This vulnerability exists within the fwparse function, which handles firmware records. It fails to properly validate the size of these records against the firmware data, leading to situations where the system can read or write data beyon...

CVE-2026-80635

A flaw was found in the Linux kernel's wcn36xx Wi-Fi driver. This vulnerability occurs because the driver does not adequately validate the length of certain firmware responses. An attacker could potentially craft a malicious firmware response, leading to an out-of-bounds read of stale heap data...

CVE-2026-82876

Phison PS3111-S11 controller firmware verifies RSA signatures using a public modulus embedded within the firmware image itself rather than anchored in immutable storage. Attackers can generate arbitrary RSA key pairs, sign modified firmware with the private key, embed the matching modulus in the...
