Description

An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931.

• linux linux kernel (>= 2.6.39 < 4.4.260) • linux linux kernel (>= 4.5.0 < 4.9.260) • linux linux kernel (>= 4.10.0 < 4.14.224) • linux linux kernel (>= 4.15.0 < 4.19.179) • linux linux kernel (>= 4.20.0 < 5.4.103) • linux linux kernel (>= 5.10.0 < 5.10.21) • linux linux kernel (>= 5.11.0 < 5.11.4) • linux linux kernel 5.12 • debian debian linux 9.0 • netapp cloud backup • netapp solidfire baseboard management controller firmware
