Additionally the granularity of the grant table # doesn't allow sharing less than a 4K page, leading to unrelated data # residing in the same 4K page as data shared with a backend being # accessible by such backend (CVE-2022-33741, CVE-2022-33742). # # - XSA-405 (1 patch for netfront driver, only 5.10 and newer): # # While adding logic to support XDP (eXpress Data Path), a code label # was moved in a way allowing for SKBs having references (pointers) # retained for further processing to nevertheless be freed. # # - XSA-406 (1 patch for Arm specific dom0 code): # # When mapping pages of guests on Arm, dom0 is using an rbtree to keep # track of the foreign mappings. # # Updating of that rbtree is not always done completely with the # related lock held, resulting in a small race window, which can be # used by unprivileged guests via PV devices to cause inconsistencies # of the rbtree. These inconsistencies can lead to Denial of Service # (DoS) of dom0, e.g. by causing crashes or the inability to perform # further mappings of other guests' memory pages. # # * tag 'xsa-5.19-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: # xen/arm: Fix race in RB-tree based P2M accounting # xen-netfront: restore __skb_queue_tail() positioning in xennet_get_responses() # xen/blkfront: force data bouncing when backend is untrusted # xen/netfront: force data bouncing when backend is untrusted # xen/netfront: fix leaking data in shared pages # xen/blkfront: fix leaking data in shared pages # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e35e5b6f695d241ffb1d223207da58a1fbcdff4b # < make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_pseries_le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_le_defconfig # < make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_pseries_le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_pseries_le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_pseries_le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/linus_pseries_le_defconfig_powerpc-gcc5 # Build took: 0:01:11.199282
