Title
jffs2: Prevent rtime decompress memory corruption
Summary
In the Linux kernel, the following vulnerability has been resolved: jffs2: Prevent rtime decompress memory corruption The rtime decompression routine does not fully check bounds during the entirety of the decompression pass and can corrupt memory outside the decompression buffer if the compressed data is corrupted. This adds the required check to prevent this failure mode.

No network- or peer-supplied data is on the path.\nAC:L - The attacker fully controls the compressed stream and the `dsize` field and computes matching node/data CRC32s, so decompression is entered deterministically and the 255-byte overflow fires on the first affected node with no race, timing window, or uncontrollable memory-layout condition; `CONFIG_JFFS2_RTIME` is `default y` on every JFFS2 build.\nPR:N - The attacker needs no account or privilege on the target \u2014 they only author the crafted JFFS2 image (firmware update blob, flash/SD contents, or an image file), and the privileged mount is performed by the victim, matching the pre-existing pattern for crafted-filesystem-image CVEs.\nUI:R - A victim (root or automated tooling) must mount the attacker-supplied JFFS2 image and then touch it \u2014 though a single `ls -l` over a crafted device node, or the background GC thread, is enough once mounted.\nS:U - The stack/slab/page corruption stays within the kernel of the affected host; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The same loop reads `data_in[pos++]` past `srclen` and emits those adjacent-slab bytes into file content the attacker can read back, and the 255-byte controlled overwrite is a corruption primitive readily leveraged into arbitrary kernel memory disclosure.\nI:H - Up to 255 attacker-chosen bytes are written past the destination \u2014 including past a 4-byte kernel stack union in `jffs2_iget()` (return-address overwrite) and past an attacker-sized `kmalloc()` buffer (groomable slab overflow into adjacent objects/freelist pointers), yielding control-flow hijack and privilege escalation.\nA:H - Even unweaponized, the out-of-bounds write corrupts the kernel stack, slab metadata, or an adjacent page, producing a stack-protector panic, slab-corruption BUG, or oops, and it is repeatable on every access to the crafted node."

No network- or peer-supplied data is on the path.\\nAC:L - The attacker fully controls the compressed stream and the `dsize` field and computes matching node/data CRC32s, so decompression is entered deterministically and the 255-byte overflow fires on the first affected node with no race, timing window, or uncontrollable memory-layout condition; `CONFIG_JFFS2_RTIME` is `default y` on every JFFS2 build.\\nPR:N - The attacker needs no account or privilege on the target \\u2014 they only author the crafted JFFS2 image (firmware update blob, flash/SD contents, or an image file), and the privileged mount is performed by the victim, matching the pre-existing pattern for crafted-filesystem-image CVEs.\\nUI:R - A victim (root or automated tooling) must mount the attacker-supplied JFFS2 image and then touch it \\u2014 though a single `ls -l` over a crafted device node, or the background GC thread, is enough once mounted.\\nS:U - The stack/slab/page corruption stays within the kernel of the affected host; no hypervisor, IOMMU, or sandbox boundary is crossed.\\nC:H - The same loop reads `data_in[pos++]` past `srclen` and emits those adjacent-slab bytes into file content the attacker can read back, and the 255-byte controlled overwrite is a corruption primitive readily leveraged into arbitrary kernel memory disclosure.\\nI:H - Up to 255 attacker-chosen bytes are written past the destination \\u2014 including past a 4-byte kernel stack union in `jffs2_iget()` (return-address overwrite) and past an attacker-sized `kmalloc()` buffer (groomable slab overflow into adjacent objects/freelist pointers), yielding control-flow hijack and privilege escalation.\\nA:H - Even unweaponized, the out-of-bounds write corrupts the kernel stack, slab metadata, or an adjacent page, producing a stack-protector panic, slab-corruption BUG, or oops, and it is repeatable on every access to the crafted node.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\", \"lessThan\": \"421f9e9f0fae9f8e721ffa07f22d9765fa1214d5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\", \"lessThan\": \"f6fc251baefc3cdc4f41f2f5a47940d7d4a67332\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\", \"lessThan\": \"bd384b04ad1995441b18fe6c1366d02de8c5d5eb\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\", \"lessThan\": \"47c9a7f81027a78afea9d2e9a54bfd8fabb6b3d0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\", \"lessThan\": \"6808a1812a3419542223e7fe9e2de577e99e45d1\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\", \"lessThan\": \"dc39b08fcc3831b0bc46add91ba93cd2aab50716\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\", \"lessThan\": \"fe051552f5078fa02d593847529a3884305a6ffe\", \"versionType\": \"git\"}], \"programFiles\": [\"fs/jffs2/compr_rtime.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"2.6.12\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"2.6.12\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.4.287\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.231\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.174\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.120\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.66\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.5\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.13\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"fs/jffs2/compr_rtime.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/421f9e9f0fae9f8e721ffa07f22d9765fa1214d5\"}, {\"url\": \"https://git.kernel.org/stable/c/f6fc251baefc3cdc4f41f2f5a47940d7d4a67332\"}, {\"url\": \"https://git.kernel.org/stable/c/bd384b04ad1995441b18fe6c1366d02de8c5d5eb\"}, {\"url\": \"https://git.kernel.org/stable/c/47c9a7f81027a78afea9d2e9a54bfd8fabb6b3d0\"}, {\"url\": \"https://git.kernel.org/stable/c/6808a1812a3419542223e7fe9e2de577e99e45d1\"}, {\"url\": \"https://git.kernel.org/stable/c/dc39b08fcc3831b0bc46add91ba93cd2aab50716\"}, {\"url\": \"https://git.kernel.org/stable/c/fe051552f5078fa02d593847529a3884305a6ffe\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\njffs2: Prevent rtime decompress memory corruption\\n\\nThe rtime decompression routine does not fully check bounds during the\\nentirety of the decompression pass and can corrupt memory outside the\\ndecompression buffer if the compressed data is corrupted.
