In the Linux kernel, the following vulnerability has been resolved: clk: bcm: rpi: A NULL check has been added in raspberrypiclkregister. devmkasprintf returns NULL when memory allocation fails. Currently, raspberrypiclkregister does not check for this case, which results in a NULL pointer being...
Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: Networks: Ethernet: Device: am65-cpsw-nuss: Fixed the skb size by taking into account skbsharedinfo. While transitioning from netdevallocip Align to buildskb, memory for the “skbsharedinfo” member of an “skb” was not allocated...
Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: scsi: libiscsi: Initialize iscsiconn-dddata only if memory is allocated. In the case of an ibfastregmr allocation failure during iSER setup, the system may encounter a panic because iscsiconn-dddata is initialized unconditionally...
Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: lib/alloctag: Do not acquire an inexistent lock in alloctagtopusers. alloctagtopusers attempts to lock alloctagcttype-modlock, even when alloctagcttype is not allocated. This occurs because: 1. Allocating tags is disabled since m...
Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: Input: cs40l50-vibra – fixed the potential NULL dereferencing in cs40l50Uploadowt. The cs40l50Uploadowt function allocates memory using kmalloc, without checking for allocation failures. This could lead to a NULL pointer...
Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: TCP: Proper signedness in the calculation of remaining space in an skb object. Syzkaller reported a bug 1 where sk-skforwardalloc could overflow. When we send data, if an skb object exists at the end of the write queue, the kerne...
