Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: fixed a potential memory leak in ext4fcrecordregions. Since krealloc may return NULL, in this case, ‘state-fcregions’ may not be freed by krealloc. However, ‘state-fcregions’ is already set to NULL. This could lead to a...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ksmbd: A possible reference count leak in smb2open has been fixed. The reference count of ACLs will cause a leak when memory allocation fails. This issue has been addressed by adding the missing posixaclrelease function...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net: fec: fixed the potential memory leak in fecenetinit. If the memory allocated for cbdbase fails, it should free the memory allocated for the queues; otherwise, a memory leak will occur. And if the memory allocated for the...

Astra Linux – Vulnerability in imagemagick

ImageMagick prior to version 7.1.2-15 contains a heap-buffer-overflow read vulnerability in GetPixelIndex, which is caused by OpenPixelCache updating image channel metadata before pixel cache memory allocation is performed. Attackers can exploit this vulnerability to trigger memory and disk...
