However, the only user of this field, namely bpfxdpfragsincreasetail...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: drm/shmem-helper: The erroneous “put” operation has been removed from the error path. The drmgemshmemmmap function does not have a reference in the error code path, resulting in the dma-buf shmem GEM object being freed...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: dma: Fixed the call order in dmamfreecoherent. dmamfreecoherent frees a DMA allocation, making the freed vaddr available for reuse. Then, it calls devresDestroy to remove and free the data structure used to track the DMA...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: i3c: mipi-i3c-hci: Fixed out-of-bounds access in hcidmairqhandler. Do not loop over ring headers in hcidmairqhandler, which are not allocated and enabled in hcidmainit. Otherwise, out-of-bounds access will occur when accessing...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: Ethernet: Aeroflex – Fix for a potential skb leak in grethinitrings The grethinitrings function does not free the newly allocated skb when dmamappingerror returns an error. Therefore, adding devkfreeskb is necessary to fix this...
