In the Linux kernel, the following vulnerability has been resolved: ata: libata-transport: fixed error handling in atatdevadd In atatdevadd, the return value of transportadddevice is not checked. As a result, a null-ptr-deref occurs when removing the module, because transportremovedevice is calle...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf: devmap: provide rxq after redirect The rxq structure contains a pointer to the device from which the redirect occurred. Currently, the BPF program that is executed after a redirect via BPFMAPTYPEDEVMAP does not set this...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: HID: pidff: Fixed null pointer dereferencing in pidfffindfields This function triggered a null pointer dereference if it was used to search for a report that wasn’t implemented on the device. This occurred both for optional and...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: cifs: avoided NULL pointer dereferencing in debug calls. The cifsserverdbg function assumes that the server variable is non-NULL. Therefore, the calling sequence has been modified to avoid NULL pointer dereferencing. Identifie...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ipvs: fixed the NULL pointer dereference in the route error path of ipv4 null-ptr-deref. The IPv4 code path in ipvsgetoutrt calls dstlinkfailure, without ensuring that skb-dev is set. This leads to a NULL pointer dereference in...
