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: fbdev: vt8500lcdfb: fixed the issue where dmafreecoherent was not called when memory was freed. The fbi-fb.screenbuffer is allocated using dmaalloccoherent, but it is not freed if an error path occurs...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/rds: fixed the possible null dereference of cp The cp parameter may be null. Calling cp-cpconn would result in a null dereference. Simon Horman adds: Analysis: cp is a parameter of rdsrdmamap, and it is not reassigned. The...

In the Linux kernel, the following vulnerability has been resolved: mmc: jz4740: Apply DMA engine limits to maximum segment size Follow the approach used in other DMA-enabled MMC host drivers see host/mmci.c, and limit the maximum segment size based on the capabilities of the DMA engine. This is...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: xdp: generate a warning when the calculated tailroom is negative Many Ethernet drivers report that the xdp Rx queue frag size is the same as the DMA write size. However, the only user of this field, namely bpfxdpfragsincreasetail...

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: Net: Ethernet: ecbhf: Fixed the dmafreecoherent function’s DMA handle. In the error-prone implementation of dmafreecoherent, it incorrectly uses priv-rxbuf.alloclen as the DMA handle. This could result in improper unmapping of th...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: spi: s3c64xx: fixed NULL dereferencing on driver unbind. A change that moved DMA channel allocation from probe back to s3c64xxspipreparetransfer failed to remove the corresponding deallocation from remove. The bogus DMA channel...

In the Linux kernel, the following vulnerability has been resolved: tty: serial: fsllpuart: disable dma rx/tx use flags in lpuartdmashutdown lpuartdmashutdown tears down the lpuart DMA mechanism, but lpuartFlushBuffer may still occur. This attempt to access DMA APIs occurs if the lpuartDMATXuse...

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: Wifi: ath10k – Fix for the dmafreecoherent pointer dmaalloccoherent allocates a DMA-mapped buffer and stores the addresses in XXXunaligned fields. These addresses should be reused when freeing the buffer, rather than using the...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: net: lltemac: Ensure that the skb is freed when it is completely used. By using the TX BD to track the skb pointer, we can efficiently free the skb buffer after a frame has been transmitted. However, to avoid freeing the skb whil...
