Kerentanan Insertion of Sensitive Information into Externally-Accessible File or Directory pada linux kernel, canonical ubuntu linux. Skor CVSS 3.1 8.8 (High) menurut NVD.

Deskripsi (NVD)

In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, several locations which shift ids translate user/group ids before performing operations in the lower filesystem were translating them into init_user_ns, whereas they should have been translated into the s_user_ns for the lower filesystem. This resulted in using ids other than the intended ones in the lower fs, which likely did not map into the shifts s_user_ns. A local attacker could use this to possibly bypass discretionary access control permissions.
