Title
jfs: fix slab-out-of-bounds read in ea_get()
Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: fix slab-out-of-bounds read in ea_get()
During the "size_check" label in ea_get(), the code checks if the extended
attribute list (xattr) size matches ea_size. If not, it logs
"ea_get: invalid extended attribute" and calls print_hex_dump().
Here, EALIST_SIZE(ea_buf->xattr) returns 4110417968, which exceeds
INT_MAX (2,147,483,647). Then ea_size is clamped:
int size = clamp_t(int, ea_size, 0, EALIST_SIZE(ea_buf->xattr));
Although clamp_t aims to bound ea_size between 0 and 4110417968, the upper
limit is treated as an int, causing an overflow above 2^31 - 1. This leads
"size" to wrap around and become negative (-184549328).
The "size" is then passed to print_hex_dump() (called "len" in
print_hex_dump()), it is passed as type size_t (an unsigned
type), this is then stored inside a variable called
"int remaining", which is then assigned to "int linelen" which
is then passed to hex_dump_to_buffer(). In print_hex_dump()
the for loop, iterates through 0 to len-1, where len is
18446744073525002176, calling hex_dump_to_buffer()
on each iteration:
for (i = 0; i < len; i += rowsize) {
linelen = min(remaining, rowsize);
remaining -= rowsize;
hex_dump_to_buffer(ptr + i, linelen, rowsize, groupsize,
linebuf, sizeof(linebuf), ascii);
...
}
The expected stopping condition (i < len) is effectively broken
since len is corrupted and very large. This eventually leads to
the "ptr+i" being passed to hex_dump_to_buffer() to get closer
to the end of the actual bounds of "ptr", eventually an out of
bounds access is done in hex_dump_to_buffer() in the following
for loop:
for (j = 0; j < len; j++) {
if (linebuflen < lx + 2)
goto overflow2;
ch = ptr[j];
...
}
To fix this we should validate "EALIST_SIZE(ea_buf->xattr)"
before it is utilised.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\njfs: fix slab-out-of-bounds read in ea_get()\n\nDuring the \"size_check\" label in ea_get(), the code checks if the extended\nattribute list (xattr) size matches ea_size. If not, it logs\n\"ea_get: invalid extended attribute\" and calls print_hex_dump().\n\nHere, EALIST_SIZE(ea_buf-\u003exattr) returns 4110417968, which exceeds\nINT_MAX (2,147,483,647). Then ea_size is clamped:\n\n\tint size = clamp_t(int, ea_size, 0, EALIST_SIZE(ea_buf-\u003exattr));\n\nAlthough clamp_t aims to bound ea_size between 0 and 4110417968, the upper\nlimit is treated as an int, causing an overflow above 2^31 - 1. This leads\n\"size\" to wrap around and become negative (-184549328).\n\nThe \"size\" is then passed to print_hex_dump() (called \"len\" in\nprint_hex_dump()), it is passed as type size_t (an unsigned\ntype), this is then stored inside a variable called\n\"int remaining\", which is then assigned to \"int linelen\" which\nis then passed to hex_dump_to_buffer(). In print_hex_dump()\nthe for loop, iterates through 0 to len-1, where len is\n18446744073525002176, calling hex_dump_to_buffer()\non each iteration:\n\n\tfor (i = 0; i \u003c len; i += rowsize) {\n\t\tlinelen = min(remaining, rowsize);\n\t\tremaining -= rowsize;\n\n\t\thex_dump_to_buffer(ptr + i, linelen, rowsize, groupsize,\n\t\t\t\t linebuf, sizeof(linebuf), ascii);\n\n\t\t...\n\t}\n\nThe expected stopping condition (i \u003c len) is effectively broken\nsince len is corrupted and very large. This eventually leads to\nthe \"ptr+i\" being passed to hex_dump_to_buffer() to get closer\nto the end of the actual bounds of \"ptr\", eventually an out of\nbounds access is done in hex_dump_to_buffer() in the following\nfor loop:\n\n\tfor (j = 0; j \u003c len; j++) {\n\t\t\tif (linebuflen \u003c lx + 2)\n\t\t\t\tgoto overflow2;\n\t\t\tch = ptr[j];\n\t\t...\n\t}\n\nTo fix this we should validate \"EALIST_SIZE(ea_buf-\u003exattr)\"\nbefore it is utilised."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: jfs: correcci\u00f3n de lectura fuera de los l\u00edmites de slab en ea_get(). Durante la etiqueta \"size_check\" en ea_get(), el c\u00f3digo comprueba si el tama\u00f1o de la lista de atributos extendidos (xattr) coincide con ea_size. De lo contrario, registra \"ea_get: atributo extendido no v\u00e1lido\" y llama a print_hex_dump(). En este caso, EALIST_SIZE(ea_buf-\u0026gt;xattr) devuelve 4110417968, que excede INT_MAX (2147483647). A continuaci\u00f3n, se fija ea_size: int size = clamp_t(int, ea_size, 0, EALIST_SIZE(ea_buf-\u0026gt;xattr)); Aunque clamp_t busca limitar ea_size entre 0 y 4110417968, el l\u00edmite superior se trata como un entero, lo que provoca un desbordamiento por encima de 2^31 - 1. Esto hace que \"size\" se repita y se vuelva negativo (-184549328). El \"size\" se pasa a print_hex_dump() (llamado \"len\" en print_hex_dump()) como tipo size_t (un tipo sin signo). Este se almacena en una variable llamada \"int remaining\", que se asigna a \"int linelen\", que a su vez se pasa a hex_dump_to_buffer(). En print_hex_dump(), el bucle for itera desde 0 hasta len-1, donde len es 18446744073525002176 y llama a hex_dump_to_buffer() en cada iteraci\u00f3n: for (i = 0; i \u0026lt; len; i += rowsize) { linelen = min(remaining, rowsize); remaining -= rowsize; hex_dump_to_buffer(ptr + i, linelen, rowsize, groupsize, linebuf, sizeof(linebuf), ascii); ... } La condici\u00f3n de detenci\u00f3n esperada (i \u0026lt; len) se rompe efectivamente ya que len est\u00e1 da\u00f1ado y es muy grande. Esto eventualmente lleva a que \"ptr+i\" se pase a hex_dump_to_buffer() para acercarse al final de los l\u00edmites reales de \"ptr\", eventualmente se realiza un acceso fuera de los l\u00edmites en hex_dump_to_buffer() en el siguiente bucle for: for (j = 0; j \u0026lt; len; j++) { if (linebuflen \u0026lt; lx + 2) goto overflow2; ch = ptr[j]; ... } Para solucionar esto debemos validar \"EALIST_SIZE(ea_buf-\u0026gt;xattr)\" antes de utilizarlo."

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\njfs: fix slab-out-of-bounds read in ea_get()\n\nDuring the \"size_check\" label in ea_get(), the code checks if the extended\nattribute list (xattr) size matches ea_size. If not, it logs\n\"ea_get: invalid extended attribute\" and calls print_hex_dump().\n\nHere, EALIST_SIZE(ea_buf-\u003exattr) returns 4110417968, which exceeds\nINT_MAX (2,147,483,647). Then ea_size is clamped:\n\n\tint size = clamp_t(int, ea_size, 0, EALIST_SIZE(ea_buf-\u003exattr));\n\nAlthough clamp_t aims to bound ea_size between 0 and 4110417968, the upper\nlimit is treated as an int, causing an overflow above 2^31 - 1. This leads\n\"size\" to wrap around and become negative (-184549328).\n\nThe \"size\" is then passed to print_hex_dump() (called \"len\" in\nprint_hex_dump()), it is passed as type size_t (an unsigned\ntype), this is then stored inside a variable called\n\"int remaining\", which is then assigned to \"int linelen\" which\nis then passed to hex_dump_to_buffer(). In print_hex_dump()\nthe for loop, iterates through 0 to len-1, where len is\n18446744073525002176, calling hex_dump_to_buffer()\non each iteration:\n\n\tfor (i = 0; i \u003c len; i += rowsize) {\n\t\tlinelen = min(remaining, rowsize);\n\t\tremaining -= rowsize;\n\n\t\thex_dump_to_buffer(ptr + i, linelen, rowsize, groupsize,\n\t\t\t\t linebuf, sizeof(linebuf), ascii);\n\n\t\t...\n\t}\n\nThe expected stopping condition (i \u003c len) is effectively broken\nsince len is corrupted and very large. This eventually leads to\nthe \"ptr+i\" being passed to hex_dump_to_buffer() to get closer\nto the end of the actual bounds of \"ptr\", eventually an out of\nbounds access is done in hex_dump_to_buffer() in the following\nfor loop:\n\n\tfor (j = 0; j \u003c len; j++) {\n\t\t\tif (linebuflen \u003c lx + 2)\n\t\t\t\tgoto overflow2;\n\t\t\tch = ptr[j];\n\t\t...\n\t}\n\nTo fix this we should validate \"EALIST_SIZE(ea_buf-\u003exattr)\"\nbefore it is utilised."
