Linux kernel security vulnerabilities

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. The Linux kernel suffers from a security vulnerability that arises from the fact that dh-dccphx is the 9th byte offset 8 of "struct dccphdr" instead of the 7th byte...

SUSE CVE-2021-46940

In the Linux kernel, the following vulnerability has been resolved: tools/power turbostat: Fix offset overflow issue in index converting The idxtooffset function returns type int 32-bit signed, but MSRPKGENERGYSTAT is u32 and would be interpreted as a negative number. The end result is that it hi...

UBUNTU-CVE-2021-47066

In the Linux kernel, the following vulnerability has been resolved: asyncxor: increase srcoffs when dropping destination page Now we support sharing one page if PAGESIZE is not equal stripe size. To support this, it needs to support calculating xor value with different offsets for each r5dev. One...

SUSE CVE-2021-46965

In the Linux kernel, the following vulnerability has been resolved: mtd: physmap: physmap-bt1-rom: Fix unintentional stack access Cast &data to char in order to avoid unintentionally accessing the stack. Notice that data is of type u32, so any increment to &data will be in the order of 4-byte...
