"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe: Don't transfer shrinker pages for pinned bos on purgeable state change\n\nPinned bos have their pages removed from the shrinker's shrinkable /\npurgeable counts on pin, and added back on unpin according to the\nbo's purgeable state at that time.\n\nHowever, xe_bo_set_purgeable_shrinker() unconditionally transfers\npages between the shrinkable and purgeable counts. If the purgeable\nstate of a pinned bo changes, for example by userspace madvising\nDONTNEED on a VMA of a bo that is also pinned as a scanout buffer,\nthis underflows one count and, after unpin, leaves the other one\npermanently inflated.\n\nOnly update the purgeable flag for pinned bos, and leave the page\naccounting to unpin.\n\n(cherry picked from commit afe6bc012034123fd838328668e609bf57e46bd3)"
