Summary
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix reference count leak in aa_pivotroot() The aa_pivotroot() function has a reference counting bug in a specific path. When aa_replace_current_label() returns on success, the function forgets to decrement the reference count of “target”, which is increased earlier by build_pivotroot(), causing a reference leak. Fix it by decreasing the refcount of “target” in that path.

La funci\u00f3n aa_pivotroot() presenta un error de conteo de referencias en una ruta espec\u00edfica. Cuando aa_replace_current_label() retorna con \u00e9xito, la funci\u00f3n olvida decrementar el conteo de referencias de \\\"target\\\", que se incrementa previamente mediante build_pivotroot(), lo que provoca una fuga de referencias. Para solucionarlo, reduzca el conteo de referencias de \\\"target\\\" en esa ruta.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":5.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"NVD-CWE-Other\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.14.1\",\"versionEndExcluding\":\"4.14.291\",\"matchCriteriaId\":\"6CA67D14-5A27-41CC-9569-F5C7E514E52B\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.15\",\"versionEndExcluding\":\"4.19.256\",\"matchCriteriaId\":\"6C47CDE3-B039-4AE5-B8E4-1DC820E473FF\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.20\",\"versionEndExcluding\":\"5.4.211\",\"matchCriteriaId\":\"B1C63D19-C08C-4308-A848-B2523C9275BD\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.5\",\"versionEndExcluding\":\"5.10.138\",\"matchCriteriaId\":\"445ACC04-A2BA-4176-B4C9-CA4AA59096D2\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.11\",\"versionEndExcluding\":\"5.15.63\",\"matchCriteriaId\":\"D5744A03-DA40-4A78-9063-13179361DC6D\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"5.19.4\",\"matchCriteriaId\":\"0E669300-DA42-4ACD-86D8-68BE5F29FB88\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:4.14:-:*:*:*:*:*:*\",\"matchCriteriaId\":\"7875AA30-1F6F-470C-A52D-ECBD6663CEC5\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:4.14:rc2:*:*:*:*:*:*\",\"matchCriteriaId\":\"B483DA9A-D449-48DE-9CA2-CEA23FD0B202\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:4.14:rc3:*:*:*:*:*:*\",\"matchCriteriaId\":\"DEF29F06-4FF7-4FE6-B66D-9D758B182CF3\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:4.14:rc4:*:*:*:*:*:*\",\"matchCriteriaId\":\"17941A19-6A3D-477F-BC6A-972D7F815FDD\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:4.14:rc5:*:*:*:*:*:*\",\"matchCriteriaId\":\"4C9B8FA6-754F-42F5-98BC-410AF7DB9F4C\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:4.14:rc6:*:*:*:*:*:*\",\"matchCriteriaId\":\"EC8F8565-B401-4F3C-B423-51F371DCB908\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:4.14:rc7:*:*:*:*:*:*\",\"matchCriteriaId\":\"C834B5F2-810F-4291-8E1F-1B32635E08F3\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:4.14:rc8:*:*:*:*:*:*\",\"matchCriteriaId\":\"BB4A96BC-72CC-4EF1-916C-9ED7177C196E\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/11c3627ec6b56c1525013f336f41b79a983b4d46\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/2ceeb3296e9dde1d5772348046affcefdea605e2\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/3ca40ad7afae144169a43988ef1a3f16182faf0a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/64103ea357734b82384c925cba4758fdb909be0c\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/d53194707d2a1851be027cd74266b96ceff799d3\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/ef6fb6f0d0d8440595b45a7e53c6162c737177f4\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/f4d5c7796571624e3f380b447ada52834270a287\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}"
